Add place detail proxy with Nominatim-first routing and Overpass fallback

New /api/place/<osm_type>/<osm_id> endpoint returns cleaned OSM tag data
for PlaceDetail panel enrichment. Routes to local Nominatim (Idaho coverage)
first, falls back to Overpass public API for out-of-region queries. Responses
cached in SQLite (data/place_cache.db) with no expiry.

New modules: lib/place_detail.py (proxy + cache), lib/osm_categories.py
(~50 category humanization mappings). Profile YAMLs updated with
place_details config block and has_nominatim_details flag.
