This update enhances support for JSON fields in the MustBeApproved trait. Changes include modifications to getDirtyAttributes and callCastAttribute methods to handle JSON casting. Extended tests are also added to validate the correct functionality with Models containing JSON fields.

This commit removes the user authentication check from the MustBeApproved trait. This change ensures that the trait is solely focused on approval processes and not concerned with user authentication, making for cleaner code and separation of concerns.
