Remove experimental Bluetooth key transfer module

Browse Source 
- Deleted BluetoothKeyTransfer.js and related classes
- Removed BluetoothKeyTransfer.jsx UI component
- Cleaned up Bluetooth imports from app-boot.js and bootstrap-modules.js
- Removed Bluetooth buttons and handlers from main app
- Eliminated all Bluetooth functionality due to Web Bluetooth API limitations
- Browsers cannot create GATT servers or advertise devices
- Reduced bundle size by ~78KB
- Application now focuses on supported browser technologies (QR codes, manual key exchange, WebRTC)
