feat(warehouse): Batch 7 — Import Arrive Queue (arrived import trains, read-only)
- SchedulingReadFacade: importArriveQueue() + importTrainDetail() — read-only SELECTs only, direction derived from origin/destination station countries (route-based), so EXPORT/DOMESTIC trains are excluded. Per-train booking/container/cargo counts. - GET /warehouse-inventory/import/arrive-queue + /import/trains/:scheduleId/items - Import tab restructured into sub-tabs: Arrive Queue (implemented) / Unloaded Queue / Dispatch Queue (placeholders for next batch) - ImportArriveQueueTab: train table (schedule id, train #, route, origin, destination, arrival, bookings/containers/cargoes, status) with Open (expandable assigned-items detail) + Auto Unload (reuses existing per-booking unload endpoint over the train's bookings) - Batch7TestDataSeeder: 1 arrived IMPORT train (SEED-IMP-001) + 1 arrived EXPORT train (SEED-EXP-001, proves exclusion); idempotent - Train schedule service logic untouched (facade is SELECT-only) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
