/**
 * Unit tests for the DI-native MapsService — MAPS-001 through MAPS-110.
 * Moved 1:1 from the legacy tests/unit/services/mapsService.test.ts when the
 * maps domain folded into src/nest/maps/ (case IDs preserved; the wrapper
 * suite's delegation cases died with the delegation itself — the kill-switch,
 * photoBytesPath and bridge cases live at the bottom).
 * 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.
