feat(search): implement Search module with Typesense full-text & geo search

Browse Source 
- TypesenseClient service with configurable connection
- Collection schema for listings with facets, geo-point, and Vietnamese text
- ListingIndexer service with PostGIS coordinate extraction for geo search
- CQRS commands: SyncListing, ReindexAll (batch with pagination)
- CQRS queries: SearchProperties (filters, sorting), GeoSearch (radius)
- Event handlers for listing.approved/updated/deactivated auto-sync
- REST endpoints: GET /search, GET /search/geo, POST /search/reindex (admin)
- DTOs with class-validator validation and pagination
