feat(inventory): display all warehouse items on selection and track withdrawal recipient

- Show all available inventory items immediately when selecting a warehouse in withdrawal form
- Add vertical scrolling container with max height to prevent layout overflow for large item lists
- Add Material column to the inventory rows table for clear item identification
- Add required 'delivered_to' recipient field in withdrawal form with frontend validation
- Track delivered_to in database, models, schemas, and API
- Display recipient badge on withdrawal cards in daily control page
- Group daily control withdrawals by inventory ID and recipient

+The databases are **not** in git — Docker volumes hold the data, and

+database dumps must never be committed (they contain user rows and signing

-|---|---|
+   `postgres_data` volume; then run the seeders:
-| `casdoor.dump` | Casdoor schema + console admin (`admin` / `123`), org `inventory`, app `inventory-app`, the JWT signing cert, and the single org user `ali.mohaghegh` |
-| `procurement.dump` | Procurement schema + the single `users` row «علی محقق» with role `admin`; all other tables empty (categories/units re-seed at API startup) |
 
-⚠️ This **replaces all data** in the `procurement` and `casdoor` databases.
-On a running stack:
-
-```powershell
-docker compose stop api casdoor
-docker cp "backups/علی محقق/procurement.dump" procurement-postgres:/tmp/
-docker cp "backups/علی محقق/casdoor.dump" procurement-postgres:/tmp/
-docker exec procurement-postgres pg_restore -U postgres -d procurement --clean --if-exists /tmp/procurement.dump
-docker exec procurement-postgres pg_restore -U postgres -d casdoor    --clean --if-exists /tmp/casdoor.dump
-docker compose start casdoor api
-```
-
-Login afterwards: `ali.mohaghegh` / `hulkfuck002` (Casdoor rejects spaces
-in usernames, so «ali mohaghegh» is not a valid login name).
-
-Want demo data instead? Two seeders are still available (they create
-different users — see the Login table above):
-
-1. **App seeder** (realistic demo dataset; keeps the Casdoor org as-is):
    ```powershell
+   # Casdoor org + app + users (prints/generates credentials — do not commit them)
+   docker compose run --rm -e CASDOOR_BASE=http://casdoor:8000 api python tools/seed_casdoor.py
+   # Demo dataset (optional):
    docker exec procurement-api sh -c "cd /srv/backend && python -m tools.seed"
    ```
-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
+   docker exec procurement-postgres pg_dump -U postgres -d procurement -Fc > /srv/erp/backups/procurement-$(date +%F).dump
+   docker exec procurement-postgres pg_dump -U postgres -d casdoor    -Fc > /srv/erp/backups/casdoor-$(date +%F).dump
    ```
 
-To create a fresh dump of your own current state: stop `api` + `casdoor`,
+   Restore with `pg_restore --clean --if-exists` (stop `api` + `casdoor`
-`docker exec procurement-postgres pg_dump -U postgres -d procurement -Fc`
+   first — this **replaces all data**). The scheduled backup sidecar
-(+ the `casdoor` DB) into `backups/`, then start them again.

+Why this exists

+File downloads require an ``Authorization: Bearer`` header, but a browser

+Instead we mint a short-lived HMAC token scoped to a single attachment and

+# 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?

+**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

+# 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

+# 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`.
