feat(warehouse): Batch 8 — Import Auto Unload Arrived Bookings (→ UNLOADED)

- New UNLOADED inventory status (train-arrival landing state) + transitions + unloaded_at column
  (idempotent migration 1791000000003) + INVENTORY_UNLOADED activity type
- POST /warehouse-inventory/import/auto-unload-arrived-bookings { scheduleId }: validates ARRIVED
  IMPORT train, unloads all eligible assigned bookings (IN_TRANSIT/ARRIVED_AT_*) into UNLOADED,
  records unloadedAt + activity. Does NOT store and does NOT inspect. Reuses allocation + inventory
  plumbing. Returns { unloadedCount, skippedCount, failedCount, results }.
- Arrive Queue "Auto Unload Arrived Bookings" button now calls the new endpoint (was per-booking loop)
- Import → Unloaded Queue tab: lists UNLOADED items via InventoryWorkbench (existing actions preserved:
  Inspect/Store/Move/History) + a Last Mile action shown ONLY when booking requested door delivery
- Batch8TestDataSeeder: sets seed import train bookings to IN_TRANSIT (unload-eligible)
- Verified: auto-unload → 1 UNLOADED (unloadedAt set, not stored, not inspected); ineligible skipped;
  idempotent re-run skips already-unloaded
