feat(cache): implement Redis caching for search & analytics hot paths

- Add TTL-specific cache durations: district stats (5min), market report (15min), heatmap (5min)
- Add Redis caching to GeoSearch handler with 60s TTL
- Add cache invalidation on listing.approved, listing.updated, listing.deactivated, listing.sold events
- Invalidate search, geo_search, and all analytics cache prefixes on listing state changes
- Update tests for new CacheService dependency in event handler and geo-search handler
