feat: Add DeviceOfflineView to handle offline state for devices

- Introduced a new DeviceOfflineView widget to display a message when the device is offline.
- Updated lyfi_view.dart to use DeviceOfflineView based on device online status.
- Refactored manual_editor_view.dart, sun_editor_view.dart, settings_screen.dart, and other files to replace lyfi_driver with lyfi_coap_driver.
- Implemented BorneoCoapClient to manage CoAP requests and handle offline detection.
- Enhanced BorneoLyfiCoapDriver to support new device capabilities and status checks.
- Updated driver metadata to reflect changes in driver implementation.
- Improved error handling and logging for device operations.
