Add CancellationToken support to controller methods

Updated `CreateAction`, `CreateFakeAction`, and `GetActions`
methods in `RecActionController` to include a `CancellationToken`
parameter. This enables handling of cancellation requests during
asynchronous operations. Updated `mediator.Send` calls to pass
the `CancellationToken`, improving responsiveness and resource
management.
