Add Delete method for fake profile in OutResController

Added a new `Delete` method to the `OutResController` class to
delete all output results for a fake/test profile. The method
is accessible via the `DELETE /fake` route and supports
cancellation via a `CancellationToken`.

Included XML documentation for the method, describing its
purpose, parameters, and return type. Added `[ProducesResponseType]`
attributes to specify possible HTTP response codes: `204 No Content`
for success and `400 Bad Request` for invalid requests.

The method uses `IMediator` to send a `DeleteOutResCommand`
with a `ProfileId` obtained from the `IConfiguration` instance.
