auto-claude: subtask-5-1 - Remove orientation restriction to allow all orientations

Removed SystemChrome.setPreferredOrientations call that was restricting
the app to landscape-only mode. The app now supports all device orientations
by using Flutter's default behavior.

Also fixed a minor lint warning by replacing (_, __) with named parameters.
