feat: add Warehouses + Integrations modules, /admin/configuracion page

- Schema v0.3: Warehouse + Integration models (db push applied)
- WarehousesModule: CRUD, set-default, multi-warehouse support
- IntegrationsModule: 26 keys across 7 groups (payment, notifications,
  customs, courier, marketplace, compliance, warehouse)
- AuthService: suite address pulled from default Warehouse in DB (env fallback)
- AuthModule: imports WarehousesModule
- Seed: creates default warehouse from WAREHOUSE_ADDRESS_* env vars
- Web: /admin/configuracion page (3 tabs: Bodegas, Integraciones, Estado APIs)
- Web: admin layout adds Configuracion nav link
- api.ts: warehouses + integrations client methods
