Implement custom roles and improve permissions logic

The commit refactors the handling of account roles and enhances permissions checks. The account role has been shifted to use a string type, providing the ability to define custom roles. It also introduces the RolesDataProvider component, which stipulates role-related data for different forms and tables. The modification goes further to consider user role hierarchy in permissions checks, offering a more granular access control.
