feat(frontend): add PWA support (service worker, manifest, pwa util)

- src/service-worker.ts: cache-first app shell (build + static assets),
  network-only for /api/, offline fallback to SPA shell
- static/manifest.webmanifest: name/short_name Tanabata, theme #312F45,
  standalone display, start_url /files, icon paths for 192/512/maskable
- src/lib/utils/pwa.ts: resetPwa() — unregisters SW + clears all caches
- app.html: link manifest, theme-color meta, Apple PWA metas
- settings page: refactored to use resetPwa() from utils

Note: add /static/images/icon-192.png, icon-512.png, icon-maskable-512.png
for full installability.
