Add POST endpoint to create ResultView in controller

Added a new HTTP POST action to ResultViewController that accepts a CreateResultViewCommand in the request body. On success, it returns a 201 Created response with a reference to the Get action for the created resource. This enables clients to create new ResultView entries via the API.
