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)

+### 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.
