- Added a `roles` column to the `users` table using a JSONB data type.
- Updated the `User` entity to include role management methods (`getRoles`, `addRole`, `removeRole`).
- Modified the `UserType` form to allow selecting special roles.
- Updated Twig templates to display assigned roles in the user list.
- Added new translations for roles and updated French translation keys in `messages.fr.yml`.
