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
