feat: use filtered geo queries for catalog pages

- /hubs/[id]: use findProductsForHub to show only deliverable products
- /offers/[productId]: use findHubsForProduct to show only reachable hubs
- /suppliers/[id]/[productId]: use findSupplierProductHubs for supplier-specific hubs
- Add new GraphQL operations for geo queries
