Pull Request Overview
This PR fixes a bug in the Windows snackbar registration logic by adjusting the check for the number of windows open during the application shutdown.
- Changed the condition from checking for 1 open window to checking for 0 open windows in the OnClosed method.
- Ensures that notifications are unregistered only when there are no open windows, preventing crashes during app shutdown.

- The condition has been correctly updated from a check against 1 to 0, which should ensure that snackbar notifications are unregistered only when no windows remain. Please verify that this logic aligns with the overall lifecycle management of window events during app shutdown.
else if (Application.Current.Windows.Count is 0)

There was a previous attempt to fix this but it set window count to unregister at 1 and not zero. After verifying that when app exits it does call LifeCycle events for
OnClosedduring shutdown whenApplication.Currentis not null and windows count is zero I created this PR to address the issue.
