Ole-Morten Duesund e8428de775 Add progressive web app companion for cross-platform access

Vite + TypeScript PWA that mirrors the Android app's core features:
- Pre-processed shelter data (build-time UTM33N→WGS84 conversion)
- Leaflet map with shelter markers, user location, and offline tiles
- Canvas compass arrow (ported from DirectionArrowView.kt)
- IndexedDB shelter cache with 7-day staleness check
- Service worker with CacheFirst tiles and precached app shell
- i18n for en, nb, nn (ported from Android strings.xml)
- iOS/Android compass handling with low-pass filter
- Respects user map interaction (no auto-snap on pan/zoom)
- Build revision cache-breaker for reliable SW updates

randombytes

randombytes from node that works in the browser. In node you just get crypto.randomBytes, but in the browser it uses .crypto/msCrypto.getRandomValues

var randomBytes = require('randombytes');
randomBytes(16);//get 16 random bytes
randomBytes(16, function (err, resp) {
  // resp is 16 random bytes
});
