fix(ui): manual modal dragging, maximize/restore icon, day-toggle style

Browse Source 
- Drive modal title-bar dragging manually via pointer capture + Window.Position;
  Avalonia 12's BeginMoveDrag and VisualRoot-as-Window cast no longer work
  (VisualRoot is a TopLevelHost). Applies to ModalShell and WorktreeModalView.
- Toggle the MainWindow maximize button between maximize/restore glyphs on
  WindowState changes (adds Icon.WinRestore geometry).
- Add the ToggleButton.day-toggle style used by the Prime weekday picker row.
