fix: Skip reverse geocode for basemap label clicks

When clicking a basemap label (city, town, POI), we already know the
entity from the label properties (name, kind, wikidata). Running
fetchReverse at those coordinates would return the nearest POI which
could be a different entity (e.g., clicking Portland returns Stumptown
Coffee), corrupting the place identity.

Now skips reverse geocode when source=basemap_label and raw.kind exists.
The wikidata lookup path still handles fetching boundaries and OSM data.
