fix(catalog): resolve material category through the linked supplier (v2.7 follow-up)

v2.7 dropped materials.category_id and the API started returning category: null for
every material, but the frontend still read material.category as the material's label.
Effect: the edit page's material field rendered blank for every row, the dashboard
category filter listed nothing (and matched nothing), the wizard's category suggestions
were empty, and the conversion lookups keyed by category (refConverted →
categoryUnits/unitConversions) silently returned null, dropping the per-reference-unit
price. Saving an edited quote matched materials on an always-true category term, so two
materials sharing brand+specs were interchangeable.

Auditing the dropped column also turned up four places still dereferencing it, one
request away from a 500 and hidden only because the inventory is empty:
GET /inventory (serializer), GET /inventory?category_id=…, GET /inventory/materials/options
and DELETE /material-categories/{id}.

Backend:
- expand_service: category_by_material() resolves a material's display category from its
  FIRST linked supplier (oldest supplier_materials row — the v2.5 trigger's rule), used by
  the material and line-item payloads; category_id is populated again when not expanded.
- inventory: list filter, row serializer and material-options filter match through
  supplier_materials ⋈ suppliers, mirroring GET /materials?category_id=…
- material_categories: the delete guard blocks on suppliers (the RESTRICT FK) and says so.

Frontend:
- Material.category → Material.supplier_category (supplier-derived, documented); the
  rename pushed every read site through tsc.
- Labels use the material's own name; the edit modal field is «متریال» and prefills by
  name; formatMaterialTitle no longer falls back to a category.
- Identity matching (edit modal, wizard, material memory) is name + brand + specs via a
  shared matchMaterial(), so same-brand same-spec materials are not conflated; legacy
  composed names are still found through materialBaseName().
- Filters read the supplier's category (dashboard options + quote filter, consistent with
  the backend's quote filtering); supplier categories now come from the supplier FK
  instead of the removed JSONB column. Conversion keys use supplier_category.
- Removed dead code carrying the old logic: two uncalled topicCategories copies and
  materialOptions' unused "cat" branch.

Verified: both images build clean (tsc -b && vite build); the API was exercised in-process
against a restore of the current production dump with an inventory row added — material
and line-item payloads carry the supplier category, the inventory endpoints that used to
raise return 200, and the category delete guard returns 409 instead of 500.

-2. **Casdoor seeder** (creates org `inventory` + app + users razaei /
-   mousavi / mohaghegh / tester — run once after a fresh volume):
+
+2. **Restore your own dump** — create dumps on the server (kept server-side,
+   e.g. `/srv/erp/backups/`), never in git:
+
    ```powershell
-   python backend/tools/seed_casdoor.py   # from the host, or from the api container

    ```
 
-To create a fresh dump of your own current state: stop `api` + `casdoor`,
-`docker exec procurement-postgres pg_dump -U postgres -d procurement -Fc`
-(+ the `casdoor` DB) into `backups/`, then start them again.
+   Restore with `pg_restore --clean --if-exists` (stop `api` + `casdoor`

+# Operations runbook
+
+Day-2 operations for the ERP stack: deploys, health, backups, monitoring.
+Secrets and rotation live in [`SECRET-MANAGEMENT.md`](SECRET-MANAGEMENT.md);
+Casdoor/auth details in [`casdoor-auth.md`](casdoor-auth.md).
+
+## Deploy flow (push-to-deploy)
+
+1. Work lands on `production` only via merge from a feature branch.
+2. Every push to `production` hits the webhook receiver (host port 9000),
+   which verifies the Gitea HMAC signature, rebuilds
+   `docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d --build`
+   and then polls `/health/ready` (defaults to
+   `https://$API_HOST/health/ready` from `.env`).
+3. A failed build or a failed readiness check is a **failed deploy**:
+   `journalctl -u erp-deploy-webhook -n 200` on the VPS.
+   Rollback: `docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d --no-build`
+   after `git revert` + rebuild — or re-push the previous commit.
+
+## Health endpoints (unauthenticated, for probes)
+
+| Endpoint | Meaning |
+|---|---|
+| `GET /health` | liveness — process is up |
+| `GET /health/ready` | readiness — Postgres + MinIO + Casdoor all reachable (503 + per-check booleans when degraded) |
+| `GET /metrics` | Prometheus exposition (scraped by the monitoring stack) |
+
+## Backups
+
+The `db-backup` sidecar dumps BOTH databases (`procurement`, `casdoor`)
+with `pg_dump -Fc` every `BACKUP_INTERVAL_SECONDS` (default daily) into
+`BACKUP_DIR` (default `./backups` → set to `/srv/erp/backups` on the VPS),
+keeping `BACKUP_KEEP_DAYS` (default 14) days.
+
+Restore (⚠️ replaces all data — stop `api` + `casdoor` first):
+
+```bash
+cd /srv/erp && docker compose -f docker-compose.yml -f docker-compose.prod.yml stop api casdoor
+docker cp backups/procurement-<stamp>.dump procurement-postgres:/tmp/
+docker cp backups/casdoor-<stamp>.dump procurement-postgres:/tmp/
+docker exec procurement-postgres pg_restore -U postgres -d procurement --clean --if-exists /tmp/procurement-<stamp>.dump
+docker exec procurement-postgres pg_restore -U postgres -d casdoor --clean --if-exists /tmp/casdoor-<stamp>.dump
+docker compose -f docker-compose.yml -f docker-compose.prod.yml start casdoor api
+```
+
+**Test the restore quarterly** on a scratch volume — an untested backup is
+a hope, not a backup. Copy archives off-box periodically (the bind mount is
+still on the same disk as the volumes).
+
+## Audit trail
+
+`audit_log` (in the `procurement` DB) records who changed what for
+role assignments, user creation, and inventory transactions. Query recent
+activity:
+
+```bash
+docker exec procurement-postgres psql -U postgres -d procurement \
+  -c "SELECT occurred_at, actor, action, entity, entity_id FROM audit_log ORDER BY occurred_at DESC LIMIT 50;"
+```
+
+`quote_events` continues to hold the quote lifecycle history (its `actor`
+is now the verified user's display name, not a raw token).
+
+## Monitoring stack
+
+Start/update (separate compose project — app rebuilds don't touch it):
+
+```bash
+cd /srv/erp
+docker compose -f monitoring/docker-compose.monitoring.yml --env-file .env up -d
+```
+
+- **Grafana** — `127.0.0.1:3001` on the VPS (SSH tunnel), admin password in
+  `.env`; the «ERP — Stack overview» dashboard auto-provisions.
+- **GlitchTip** — public on `GLITCHTIP_HOST` (browser DSN) + loopback
+  `:8001` for administration. Create backend/frontend projects there and put
+  the DSNs in `.env` (`SENTRY_DSN_BACKEND` / `SENTRY_DSN_FRONTEND`).
+- **OpenPanel** — see `monitoring/README.md` for the self-hosting setup and
+  the event list the app emits.
+- **Alerts** — Prometheus rules surface in Grafana alerting (API down,
+  5xx rate, p95 latency, disk, RAM, DB connections). Attach a notification
+  channel in the Grafana UI.
+
+Logs: every container's stdout ships to Loki via Promtail — in Grafana:
+`{compose_project="erp", compose_service="api"}`; JSON lines carry
+`request_id`, `http_status`, `duration_ms`.
+
+## Routine checks
+
+```bash
+docker compose -f docker-compose.yml -f docker-compose.prod.yml ps   # all Up/healthy?
+docker compose logs --since 10m api | grep -i error
+ls -lh /srv/erp/backups | tail                                       # dumps fresh?
+curl -fsS https://$API_HOST/health/ready | jq                        # all checks true?
+df -h /                                                              # ≥20% free (builds need headroom)

+# Secret management & rotation
+
+**Policy (short):** real credentials live only in git-ignored `.env` files —
+the server-side `/srv/erp/.env` (used by the deploy webhook and compose) and
+local dev `.env` copies. Nothing secret goes into git: not in the README,
+not in dumps, not in docs. The repo is (or was) **public** — assume anything
+ever committed is compromised and rotate.
+
+`docker-compose.prod.yml` declares every production secret as
+`${VAR:?set in .env}` so the stack **refuses to boot** on defaults.
+
+## Where each secret lives
+
+| Secret | Used by | Defined in |
+|---|---|---|
+| `POSTGRES_PASSWORD` | postgres, api | server `.env` |
+| `MINIO_ROOT_USER` / `MINIO_ROOT_PASSWORD` | minio, minio-init, api | server `.env` |
+| `CASDOOR_CLIENT_SECRET` | Casdoor application record, api | server `.env` (must match the app in the Casdoor console) |
+| `CASDOOR_ADMIN_PASSWORD` | Casdoor console admin, api (`/users/sync`) | server `.env` (rotate in the Casdoor console too) |
+| `CORS_ORIGINS`, `*_HOST`, `TRAEFIK_ACME_EMAIL` | compose / Traefik | server `.env` |
+| `GITEA_WEBHOOK_SECRET` | deploy-webhook receiver (port 9000) | server `.env` + Gitea webhook config |
+| Monitoring DSNs/keys | OpenPanel, GlitchTip, Grafana | `monitoring/.env` (server-side) |
+
+## Rotation checklist — run after any leak suspicion
+
+The production branch history contained real credentials (MinIO admin,
+Casdoor passwords, server IP, DB dumps). All of the following must be
+rotated once, on the VPS:
+
+```bash
+cd /srv/erp
+
+# 1) MinIO root — then update MINIO_ROOT_* in /srv/erp/.env
+mc alias set local http://127.0.0.1:9000 <old-user> '<old-pass>'
+mc admin user add local <new-user> '<new-pass>'      # then:
+mc admin policy attach local consoleAdmin --user <new-user>
+mc admin user remove local <old-user>
+# (simplest equivalent: mc admin user svcacct or change root via env +
+#  `docker compose up -d minio` — MinIO persists root creds from env)
+
+# 2) PostgreSQL — then update POSTGRES_PASSWORD in .env
+docker exec -it procurement-postgres psql -U postgres -c \
+  "ALTER USER postgres PASSWORD '<new-strong-password>';"
+docker compose up -d api   # api re-reads the DSN from .env
+
+# 3) Casdoor console admin (console → Identity → users → admin → reset
+#    password) — then update CASDOOR_ADMIN_PASSWORD in .env
+# 4) Casdoor application client secret (console → Applications →
+#    inventory-app → edit secret) — then update CASDOOR_CLIENT_SECRET in .env
+# 5) Seeded human users: reset each password in the Casdoor console.
+# 6) Gitea webhook secret (Gitea → repo → Settings → Webhooks) — then update
+#    GITEA_WEBHOOK_SECRET in .env and restart the receiver (systemctl restart erp-deploy-webhook)
+
+# 7) Apply everything:
+docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d
+```
+
+- **SSH**: disable password login (`PasswordAuthentication no` in
+  `/etc/ssh/sshd_config`), use keys only, and prefer a non-root user with
+  sudo over `root` direct login.
+- **Repo hygiene**: keep the repo private until the git history is either
+  purged (BFG / `git filter-repo` on the README + `backups/` blobs) or every
+  leaked value is rotated. Deleting a file in a later commit does **not**
+  remove it from history.
+- **Verify**: after rotation, `docker compose logs api | grep -i error`,
+  log into the app, upload + download one attachment, and confirm the
+  webhook deploy still works with a test push.

+# Deploy webhook receiver (push-to-deploy, hardened)
+
+Every push to the `production` branch triggers a rebuild on the VPS through
+this receiver (host port 9000). The receiver must **verify the Gitea
+webhook signature** — an open deploy endpoint is effectively remote code
+execution on the production server.
+
+## VPS setup (one time)
+
+```bash
+# 1) Files live here:
+sudo mkdir -p /srv/erp && sudo chown $USER /srv/erp
+#    copy the repo to /srv/erp (the receiver runs docker compose in this dir)
+
+# 2) Secrets — add to /srv/erp/.env (git-ignored):
+#    GITEA_WEBHOOK_SECRET=<long random string>
+
+# 3) Install as a systemd service:
+sudo cp infra/deploy-webhook/erp-deploy-webhook.service /etc/systemd/system/
+#    adjust User= and paths inside, then:
+sudo systemctl daemon-reload
+sudo systemctl enable --now erp-deploy-webhook
+curl http://127.0.0.1:9000/ping   # → {"status":"ok"}
+```
+
+## Gitea webhook
+
+Repo → Settings → Webhooks → Add webhook → Gitea:
+
+- Target URL: `http://<server-ip>:9000/deploy`
+- Method: `POST` — Secret: same value as `GITEA_WEBHOOK_SECRET`
+- Trigger: Push Events, Branch filter: `production`
+
+## Behavior
+
+- Verifies `X-Gitea-Signature` (HMAC-SHA256) — rejects everything else with 401.
+- Only pushes to `refs/heads/production` deploy; other branches are acknowledged and ignored.
+- Deploys are serialized with a lock (concurrent pushes don't race).
+- Runs `docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d --build` in `/srv/erp`.
+- After a successful build, polls the API `/health/ready` endpoint and logs
+  a failed post-deploy check (surfaced by the monitoring stack).
+- Logs to journald (`journalctl -u erp-deploy-webhook -f`).

+"""Hardened Gitea push-to-deploy webhook receiver.
+
+Replaces an unverified "POST /deploy" endpoint. Runs on the VPS (host port
+9000 is reserved for it) and rebuilds the stack when a push to the
+production branch arrives — but ONLY after verifying the Gitea webhook
+signature (HMAC-SHA256 of the raw body with GITEA_WEBHOOK_SECRET).
+
+Why this matters: an unauthenticated deploy endpoint lets anyone on the
+internet restart/rebuild the production stack (and, if it shells out to a
+script, is effectively remote code execution).

+# Monitoring & analytics stack
+
+What runs where, and why — the ERP gets the three missing observability
+layers on the same 8 GB VPS:
+
+| Layer | Tool | What it answers | Budget |
+|---|---|---|---|
+| Product analytics | **OpenPanel** (self-hosted) | Which features are used? Where do users drop out of the quote wizard? Funnel: login → wizard steps → quote submitted → accepted → received. Session replay **off** by design (heavy; revisit with sampling later) | ~1–1.5 GB |
+| Error tracking | **GlitchTip** (Sentry-compatible) | What broke, for whom, with which stack trace — frontend (ErrorBoundary + fetch errors) and backend (all unhandled exceptions) | ~750 MB |
+| Metrics + logs | **Prometheus + Grafana + Loki/Promtail + node/postgres-exporters + cAdvisor** | Request rate/latency/5xx, container RAM, Postgres connections, disk pressure; full container logs searchable in Grafana | ~1.4 GB |
+
+The monitoring compose is a **separate compose project** — push-to-deploy
+rebuilds of the app never restart monitoring containers.
+
+## First-time deployment (VPS)
+
+```bash
+cd /srv/erp   # the repo checkout used by the deploy webhook
+
+# 1) monitoring section of .env (see .env.example) — fill in real values:
+#    GLITCHTIP_SECRET_KEY, GLITCHTIP_DOMAIN/HOST, GLITCHTIP_DB_PASSWORD,
+#    GRAFANA_ADMIN_PASSWORD, POSTGRES_PASSWORD (already set), LOG_FORMAT=json
+
+# 2) the main compose gained a shared network — re-up once so it exists:
+docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d
+
+# 3) start monitoring:
+docker compose -f monitoring/docker-compose.monitoring.yml --env-file .env up -d
+
+# 4) GlitchTip is routed publicly through Traefik for the browser SDK:
+docker compose -f monitoring/docker-compose.monitoring.yml --env-file .env \
+    --profile public up -d glitchtip
+```
+
+Admin UIs stay **loopback-only** (same posture as the MinIO console):
+
+```powershell
+ssh -L 3001:127.0.0.1:3001 -L 8001:127.0.0.1:8001 <user>@<server-host>
+# Grafana  → http://localhost:3001  (dashboards auto-provisioned)
+# GlitchTip → http://localhost:8001 (create the first admin on first open)
+```
+
+In GlitchTip: create an **organization → project** for the backend and one
+for the frontend, copy the DSNs into `/srv/erp/.env`
+(`SENTRY_DSN_BACKEND`, `SENTRY_DSN_FRONTEND`) and redeploy the app once.
+
+## Product analytics (OpenPanel)
+
+Deployed from the upstream self-hosting branch (kept outside this repo —
+it ships its own compose + update tooling):
+
+```bash
+cd /opt
+git clone -b self-hosting https://github.com/Openpanel-dev/openpanel.git
+cd openpanel/self-hosting
+./setup     # interactive
+./start
+```
+
+Then:
+
+1. Open the OpenPanel dashboard (expose it via Traefik on
+   `stats.bennu-api-bahrestan.ir` following its docs — add the container to
+   `traefik_network` and give the dashboard + its `/api` path labels),
+   create a project → copy the **client id / client secret**.
+2. Put them in `/srv/erp/.env`:
+   `OPENPANEL_API_URL` (in-network URL of its api service),
+   `OPENPANEL_CLIENT_ID`, `OPENPANEL_CLIENT_SECRET`, and
+   `OPENPANEL_PUBLIC_URL` (browser-facing origin) — then rebuild the app:
+   `docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d --build api frontend`.
+
+What gets tracked automatically once configured:
+
+- **Frontend**: page views, `login_success`, `wizard_step` (funnel across
+  the 5 quote-wizard steps), `quote_submitted`, `user_identified`.
+- **Backend** (server-side, cannot be blocked by the browser):
+  `login_success`, `quote_offered/edited/accepted/arrived/expired/rejected`,
+  `receipt_confirmed` — see `backend/app/services/analytics.py`.
+
+Without the env vars everything is a no-op — the app never waits on
+analytics (3 s timeout, swallow-all).
+
+## Session replay
+
+Deliberately **off** (records full DOM of every session → storage + privacy
+costs; low value for a small internal team at launch). If wanted later:
+enable OpenPanel replay with **10–25% sampling** and review retention —
+budget +1 GB storage and re-check RAM headroom first.
+
+## Alerting
+
+`monitoring/prometheus/alerts.yml` defines: API down, 5xx > 5%, p95 > 2 s,
+root disk < 10%, host RAM < 10%, Postgres > 80 connections. They appear in
+Grafana alerting; wire a notification channel (email/Telegram) from the
+Grafana UI when ready.
+
+## Lean mode (if RAM gets tight)
+
+Drop prometheus+grafana+loki+promtail+cadvisor+node-exporter (~1.1 GB) and
+keep GlitchTip + OpenPanel only; add `uptime-kuma` (~100 MB) for
+up/down pings. The app keeps `/health/ready` either way — the deploy
+webhook uses it post-rebuild regardless of the metrics stack.
+
+## What the app exposes for this stack
+
+- `GET /health` — liveness (process up).
+- `GET /health/ready` — readiness: Postgres + MinIO + Casdoor checks.
+  Used by the deploy webhook after every rebuild.
+- `GET /metrics` — Prometheus format (unauthenticated, for scraping).
+- JSON request logs with `X-Request-ID` (set `LOG_FORMAT=json` in prod)
+  → shipped to Loki by Promtail.
+
+## Local runs (Docker Desktop)
+
+Start WITHOUT `--profile host-metrics` — node-exporter and cAdvisor need
+Linux rootfs mounts and will fail to start on Windows/macOS hosts:
+
+```bash
+docker compose -f monitoring/docker-compose.monitoring.yml --env-file .env up -d
+```
+
+Per-container and host metrics are absent locally; API metrics, Postgres
+metrics, logs, GlitchTip and Grafana all work the same. On the Linux VPS
+always include `--profile host-metrics`.
