feat: integrate NFC functionality for reading and writing tags

- Added NFCManagerRepository to handle NFC operations using react-native-nfc-manager.
- Implemented ReadNFCTagUseCase and WriteNFCTagUseCase for reading and writing NFC tags.
- Updated app layout to include NFC reader screen.
- Created WriteNFCScreen for writing NFC tags with filament data.
- Enhanced HomeScreen to support NFC reading and added NFC button in FilamentDetailScreen.
- Updated app.json to include react-native-nfc-manager dependency.
- Added animations and user feedback for NFC operations in the UI.
