This commit adds a check to the `destroy` method in the `CaptchaTokenService`. It uses the `Helpers::isDemoModeAndUserDenyUpdate` function to prevent users from deleting tokens while the application is in demo mode. This was added to protect the application's state during presentations or demos.
The Role class in app/Models has been refactored to improve readability and maintainability. The 'slug' field was replaced with 'code' for consistency with the rest of the codebase. In addition, the 'isRemove' and 'isAdmin' methods were rewritten using new 'Attribute' Eloquent cast. This refactor enhances the code's clarity, promotes better comprehension, and clears redundant code comments.
