Initial commit: Norwegian emergency shelter finder app

Browse source 
Android app (Kotlin) that locates the nearest public shelter (tilfluktsrom)
in Norway. Designed for offline-first emergency use.

Features:
- Downloads and caches all 556 Norwegian shelter locations from Geonorge
- GPS-based nearest shelter finding with distance and bearing
- OSMDroid map with offline tile caching for surroundings
- Large directional compass arrow pointing to selected shelter
- Compass sensor integration for real-time direction updates
- Shows 3 nearest shelters with distance, capacity, and address
- Toggle between map view and compass/arrow view
- Auto-caches map tiles on first launch for offline use
- Weekly background data refresh with manual force-update
- i18n: Norwegian Bokmål, Nynorsk, and English

Technical:
- EPSG:25833 (UTM33N) → WGS84 coordinate conversion
- Haversine distance and bearing calculations
- Room database for shelter persistence
- Fused Location Provider for precise GPS
- Sensor fusion (rotation vector with accel+mag fallback) for compass
