docs+data: refresh demo dumps (clean seeded state) + restore/seeder docs

- backups/procurement.dump regenerated from the clean seeded state (was the
  junk test data); README documents both the app seeder and the restore path
- docs/casdoor-auth.md: later-batch changelog (fulfillment split, demo
  seeder, API-driven topics, hub-and-spoke, count modal, FOUND ceiling,
  semantic colors)

 This **replaces all data** in the `procurement` and `casdoor` databases with
-the committed state (users + roles, projects, warehouses, quotes with
+the committed state — a clean, realistic demo: 3 projects × 2 warehouses,
-receipts, inventory rows, Casdoor org/app/users). To create a fresh dump of
+4 suppliers, 12 materials across all 8 categories, and 4 quotes covering
-your own current state:
+every lifecycle state (offered / in-transit / partially received /
+completed) with matching stock.
 
+Two alternative ways to get a clean state:
+
+1. **App seeder** (realistic demo data, keeps the Casdoor org as-is):
    ```powershell
-docker compose stop api casdoor
+   docker exec procurement-api sh -c "cd /srv/backend && python -m tools.seed"
-docker exec procurement-postgres pg_dump -U postgres -d procurement -Fc > backups/procurement.dump   # (Git Bash: use -f inside the container + docker cp)
-docker exec procurement-postgres pg_dump -U postgres -d casdoor -Fc > backups/casdoor.dump
-docker compose start casdoor api
    ```
+2. **Casdoor seeder** (creates org `inventory` + app + users razaei /
+   mousavi / mohaghegh / tester — run once after a fresh volume):
+   ```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.

+### Later batch (ledger fulfillment, demo data, hub-and-spoke)
+
+- **Ledger fulfillment split** («رسید جزیی»): the quotation card shows a
+  counter badge («رسید: X از Y قلم» / «تکمیل شد» / «در راه»); each line item
+  visually splits into its received part (رسید شده ✓ + date + warehouse from
+  the receipt allocations) and the in-transit remainder — quantities always
+  sum to the original line (totals unchanged). Display-only split, agreed to
+  keep the receipt/decision chain intact.
+- **Demo data seeder** (`backend/tools/seed.py`): wipes the app tables and
+  seeds a clean realistic dataset (3 projects × 2 warehouses, 4 suppliers,
+  12 materials across the 8 categories, 4 quotes in offered / in-transit /
+  partial / completed states with matching stock and receipts). Roles are
+  bound to the Casdoor users by username (run `seed_casdoor.py` first).
+  `backups/*.dump` are refreshed after seeding — teammates restore with
+  `backups/restore.ps1`.
+- **Topics are API-driven**: the 8-topic grids (suppliers, wizard, units)
+  now come from `/material-categories` via the store instead of a hardcoded
+  list (which had a mismatched label «ابزار و تجهیزات ساخت»).
+- **Hub-and-spoke navigation**: the tab strip lives only on «داشبورد انبار»;
+  sub-views (تغییر موجودی، کنترل روزانه، انبارها، کالاهای در راه، سازماندهی)
+  hide it and return via «بازگشت به داشبورد». «افزایش موجود» became the
+  «تغییر موجودی» entry button.
+- **Stock count**: submission goes through a confirmation modal showing
+  current vs counted vs variance (کسری/مازاد) before the STOCK_COUNT
+  transaction is posted.
+- **Found-items ceiling**: `found_qty ≤ missing balance` enforced client-side
+  (red input + inline warning, submit disabled) and server-side (422 with the
+  remaining balance); fully recovered losses drop off the pending list.
+- **Semantic colors**: emerald = inflow (خرید/برگشت/پیدا شده), rose =
+  outflow (برداشت/ضایعات/اتلاف/مفقودی), blue = neutral (انتقال/شمارش
+  موجودی) across the warehouse module; quantities are shown as absolute
+  values with color-coded badges instead of ± signs.
