feat(warehouse): add warehouse management module (batch 1)

Backend (edr-freight-api): - Warehouse, WarehouseYard, WarehouseZone, WarehouseInventory entities - CRUD for warehouses/yards/zones with scoped code uniqueness - Inventory receive with location-hierarchy + capacity validation and transactional capacity-counter updates - inspect / ready-for-loading status transitions - inventory inquiry (booking/customer/container/cargo-type joins) - migration creating freight.warehouse* tables Frontend (freight backoffice): - types, service, react-query hooks, URL constants - reusable components: badges, filters, table/card views, inventory and inquiry tables, create/receive modals - pages: Warehouse list, detail (overview/yards/zones/inventory tabs), inventory, inventory inquiry - Warehouse Information card + Receive At Warehouse on booking detail - routes + sidebar nav; app-wide ErrorBoundary Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
