feat: Add PWA support with manifest and ServiceWorker integration

- Mounted static files directory to serve PWA assets like manifest.json and ServiceWorker scripts.
- Updated `auth.html` and `keys_status.html` templates:
  - Added `<link>` for manifest and icons to support Progressive Web App (PWA) features.
  - Added meta tags for theme color and Apple web app capabilities.
  - Integrated ServiceWorker registration script for offline capabilities.
