Fix type safety in catalog composables + 3 InfoPanel bugs

- Add proper codegen types to all catalog composables:
  - useCatalogHubs: HubItem, NearestHubItem
  - useCatalogSuppliers: SupplierItem, NearestSupplierItem
  - useCatalogProducts: ProductItem
  - useCatalogOffers: OfferItem
  - useCatalogInfo: InfoEntity, ProductItem, HubItem, OfferItem

- Fix InfoPanel bugs for offers:
  - Use locationLatitude/locationLongitude for offer coordinates
  - Enrich entity with supplierName after loading profile
  - Apply-to-filter now adds both product AND hub for offers

- Filter null values from GraphQL array responses
- Add type-safe coordinate helper (getEntityCoords)
- Fix urlBounds type inference in useCatalogSearch
