fix: disable PWA for Capacitor builds

Updates PWA configuration to:
- Disable PWA features for Capacitor builds
- Add @capacitor/app dependency
- Update environment variable handling in build config

This prevents conflicts between PWA and native app functionality
when building for mobile platforms.

Technical changes:
- Add isCapacitor check to PWA disable logic
- Update VITE_PWA_ENABLED environment variable definition
- Add @capacitor/app to package dependencies

package-lock.json
