Refactor catalog to use coordinate-based GraphQL endpoints

Replace entity-specific queries (GetProductsNearHub, GetOffersByHub, GetHubsForProduct, GetSuppliersForProduct) with unified coordinate-based endpoints (NearestHubs, NearestOffers, NearestSuppliers, RouteToCoordinate). This simplifies backend architecture from 18 to 8 core endpoints while maintaining identical UI/UX behavior.

All composables and pages now use coordinates + client-side grouping instead of specialized backend queries. For global product filtering, uses center point (0,0) with 20000km radius.
