Add conflict resolution for generated API + add test

Implemented additional code to handle version conflicts when editing accompanying period work. By keeping track of the current version and returning an HTTP conflict response when it doesn't match with the provided entity version, users are properly alerted to update their entity before continuing. Furthermore, adjusted BadRequestHttpException to match correct arguments order and introduced entity version as query parameter for the URL.
