Description
Backend infrastructure component that proxies geocoding requests to an external geocoding API (e.g., Google Maps Geocoding or Nominatim) server-side, ensuring API keys are never exposed to the mobile client. Caches geocoding results in the database to minimize API call volume and costs.

Responsibilities
- Proxy address-to-coordinate geocoding requests to external API
- Cache geocoding results against address strings to avoid redundant calls
- Handle rate limiting, retries, and error responses from the geocoding provider
- Expose REST endpoint consumed by the mobile LocationService
Interfaces
geocode(address: string) -> Promise<{ lat: number; lng: number } | null>
reverseGeocode(lat: number, lng: number) -> Promise<string | null>
batchGeocode(addresses: string[]) -> Promise<GeocodingResult[]>
getCachedResult(address: string) -> GeocodingResult | null
