Add device UUID handling and improve wired settings management

- Introduce `device` and `uuid` properties to store network device and its UUID.
- Add logic to fetch and update the UUID of the active connection.
- Modify `open_wired_settings` to pass the UUID for editing specific connections.
- Refactor `update_wired_status` to use the stored `device` property.
- Update dialog creation to use the main application window as the parent.
