fix(place): add reverse geocode fallback for place details

When a place is selected without osm_type/osm_id (e.g., clicking
on a basemap label), trigger a reverse geocode to obtain the OSM
identifiers. This enables fetching place details including boundary,
wiki_summary, and other enriched data.

The existing placeDetails useEffect will then fire once the
osm_type/osm_id are available in the selectedPlace.raw object.
