Fix camera jumping when opening InfoPanel

Replace setTimeout/debounce with event-based approach:
- Add isInfoLoading computed that tracks all info loading states
- Pass infoLoading prop through CatalogPage to CatalogMap
- Watch infoLoading transition from true->false to trigger fitBounds
- Remove setTimeout hack in favor of proper loading state detection
