Optimize catalog loading: backend bounds filtering + early returns

- Add bounds (west/south/east/north) parameters to GetNodes query
- Add setBoundsFilter to useCatalogHubs, useCatalogSuppliers, useCatalogProducts
- Replace client-side bounds filtering with backend query
- Add early return to setProductFilter to avoid redundant fetches
- Watch filterByBounds to trigger backend refetch when checkbox changes
