feat(geocoding): auto-categorize places via Pelias taxonomy

Pelias hides the 'category' field from API responses unless the
caller filters by categories=... explicitly — a default intended for
keyword search that strips category metadata from address queries.

Patch the Pelias API's geojsonify_place_details.js so the category
array is returned on every feature (food, retail, transport, …),
mounted into the container as a read-only volume override.

Rewrite category-map.ts to map Pelias' OSM taxonomy to our 7
PlaceCategories using a priority-ordered list so a restaurant
tagged ['food','retail','nightlife'] resolves to 'food' (the most
specific), not 'shopping'.

Verified with Konstanz test queries:
  Konzil Restaurant        → food
  Bahnhof Konstanz         → transit
  Physiotherapie-Schule    → work
  MX-Park                  → leisure
