Add physical escape room map, reviews, and website admin

Public:
- /escape-rooms: Leaflet + OpenStreetMap map with marker clustering and a
  searchable list, both built from a cached slim JSON feed
- /escape-rooms/{id}-{slug}: room detail with a mini-map and user reviews
  (rating + title + body, login required)
- /escape-rooms/suggest: visitor submission form with click-to-drop-pin map
  and reCAPTCHA v3; new rooms land as pending

Data:
- EscapeRoom / EscapeRoomReview entities (soft-delete), migration
- app:escaperooms:import-osm console command pulls leisure=escape_game from
  the Overpass API, upserts by (osmType, osmId), skips locked rows;
  --tiled / --area / --bbox options

Admin (new "Website Admin" area, separate from Game Admin):
- src/Website/Controller/AdminEscapeRoomController.php at /admin/escape-rooms:
  status-filtered list, new/edit, publish/hide/reject, delete, review removal
- game admin sidebar extracted into a block and cross-linked

Assets: leaflet + leaflet.markercluster; escaperoom-map and escaperoom-detail
Encore entries.
