Upgraded the `SimConnect.NET` package reference in the `BARS-Client-V2.csproj` file from version `0.1.14-beta` to `0.1.15-beta`. This update may include bug fixes, new features, or other improvements provided by the library's maintainers.

Added `Dispatcher` usage to manage `_host.StartAsync()` on the UI
thread without blocking, ensuring smoother application startup.
Wrapped `_host.StopAsync()` in a `try-catch` block during shutdown
to handle exceptions gracefully and prevent crashes. Added the
`System.Windows.Threading` namespace to support these changes.

…s; implement backoff strategy for transient errors and improve reconnection logic.
