Refactor UI code for better readability and consistency

- Improved formatting of ListTile icons and text styles in settings_screen.dart, telemetry_screen.dart, usb_screen.dart, gif_picker.dart, path_editor_sheet.dart, repeater_login_dialog.dart, and room_login_dialog.dart for better readability.
- Consolidated TextStyle definitions into single lines where applicable.
- Updated notification_service.dart to enhance readability of notification ID assignment.
- Simplified function signatures in routing_sheet.dart for clarity.
- Cleaned up test assertions in usb_flow_test.dart for conciseness.
- Removed unused translations in untranslated.json to streamline localization files.
