Subject: [PATCH] Resolve XAML compiled-binding errors in MainView
 templates\n\n- Remove x:DataType from DataTemplates to avoid compiled-binding
 on Button commands.\n- Revert Buttons to runtime-binding using
 Tag+DataContext pattern without invalid x:DataType.\n- Keep inner visuals
 typed where appropriate.\n\nFixes parser errors and prior System.Object
 property resolution issues.
