Improve document caching strategy for offline navigation

- Add navigateFallbackDenylist to exclude API and auth routes
- Enhanced urlPattern to match document destination and root path
- Increase cache entries to 50 and duration to 7 days
- Add cacheableResponse for better cache control

This should enable the app to open offline after being loaded once.
