feat(places): add self-hosted geocoding with Pelias (DACH)

New mana-geocoding service (port 3018) wraps a self-hosted Pelias
instance with LRU caching and OSM→PlaceCategory auto-mapping.
All geocoding queries stay within our infrastructure — no user
location data leaves the network.

Places module integration:
- Address autocomplete search in ListView (creates place with
  name, coords, address, category in one step)
- Address search + reverse geocoding button in DetailView
- Auto-fill address via reverse geocoding during tracking
- OSM category mapping (amenity:restaurant→food, shop:*→shopping, etc.)
