fix(map): match the GL place hover tooltip to the Leaflet map (#1385)

The MapLibre/Mapbox hover showed an anchored popup with a large photo
thumbnail, completely unlike the Leaflet map's slim, cursor-following
name/category/address card. Drop the anchored photo popup for places and
render the same cursor-following overlay the Leaflet map uses (no photo,
matching fonts/padding/shadow), so the two maps hover identically.
