remove debug launching (#43485)

## Summary of the Pull Request
This pull request simplifies the application launch logic in
`App.xaml.cs` by removing debug-specific code paths and asynchronous
window initialization. The main change is to standardize the launch
process for both debug and release builds.

**Launch logic simplification:**

* Removed the `#if DEBUG` conditional compilation around the
`OnLaunched` method, so the method signature is now consistent in all
build configurations.
* Eliminated the asynchronous call to `ShowWindow()` that was previously
executed only in debug mode, streamlining the launch behavior and
removing direct window access during debugging.
