- Add hubsList resolver for paginated hub list
- Add suppliersList resolver for paginated supplier list
- Add productsList resolver for paginated product list
- Update nearestOffers to support hubUuid parameter with route calculation
- Add OfferWithRouteType for offers with embedded routes
- Add supplier_name to OfferNodeType
- Add distance_km field to NodeType (used by nearestHubs)
- Add distance_km field to OfferNodeType (used by nearestOffers)
- Expand SupplierType with name, latitude, longitude, distance_km
- Fix nearestSuppliers to return full supplier info from nodes collection
- Fix nearestHubs and nearestOffers to pass distance_km to constructors
This fixes 8 failed integration tests for nearest* endpoints.
Resolves: Cannot query field 'distanceKm' on type 'NodeType/OfferNodeType'
Remove supplier_name field from OfferNodeType constructor in resolve_nearest_offers - this field does not exist in the type definition and causes 400 errors.

- Add nearestHubs(lat, lon, radius, productUuid?) - hubs near coordinates
- Add nearestOffers(lat, lon, radius, productUuid?) - offers near coordinates
- Add nearestSuppliers(lat, lon, radius, productUuid?) - suppliers near coordinates
- Add routeToCoordinate(offerUuid, lat, lon) - route from offer to coordinates
These unified endpoints work with coordinates instead of UUIDs, simplifying
the frontend logic by removing the need for entity-specific queries like
GetProductsNearHub, GetHubsNearOffer, etc.
- Remove find_routes, find_product_routes, delivery_to_hub queries
- Rename offers_to_hub → offers_by_hub with proper phase-based routing (auto → rail* → auto)
- Add offer_to_hub query for single offer to hub connection
- Both new queries use Dijkstra-like search with transport phases
- findProductsForHub: find products deliverable to a hub
- findHubsForProduct: find hubs where product can be delivered
- findSupplierProductHubs: find hubs for supplier's product
- findOffersForHubByProduct: find offers with routes (wrapper for findProductRoutes)
Offer edges connect offer nodes to locations and are not
transport stages. Filter them out in _build_route_from_edges()
to avoid showing 0km "offer" steps in the route stepper.
