Add CancellationToken support to OutResController methods

Updated `Get` methods in `OutResController` to include a
`CancellationToken` parameter, enabling support for request
cancellation during asynchronous operations. Updated all
`mediator.Send` calls to propagate the `CancellationToken`.

Simplified the "fake/{actionId}" route by removing the explicit
assignment of `HttpContext.Response.ContentType` for non-
`ResultType.Full` cases.
