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

+ * orders of the iteratees to sort by. If `orders` is unspecified, all values
+ * are sorted in ascending order. Otherwise, specify an order of "desc" for
+ * descending or "asc" for ascending sort order of corresponding values.

+ * @param {Array[]|Function[]|Object[]|string[]} [iteratees=[_.identity]]
+ *  The iteratees to sort by.
+ * @param {string[]} [orders] The sort orders of `iteratees`.
+ * @param- {Object} [guard] Enables use as an iteratee for methods like `_.reduce`.
+ * @returns {Array} Returns the new sorted array.
