 * Unit tests for mapsService — MAPS-001 through MAPS-080.
 * Covers parseOpeningHours, buildOsmDetails, getMapsKey, reverseGeocode,
 * resolveGoogleMapsUrl (coordinate extraction + short URL / SSRF),
 * searchNominatim, fetchOverpassDetails, fetchWikimediaPhoto, searchPlaces,
 * getPlaceDetails, and getPlacePhoto (all branches including cache logic).
 * fetch is stubbed; DB and ssrfGuard are mocked.
