fix: resolve adminfront test failures and enforce role-based access control

- Fixed ReferenceErrors in UserCreatePage and UserListPage by adding missing imports and definitions.
- Implemented explicit role-based access control (forbidden messages) in UserCreatePage and UserDetailPage.
- Corrected Playwright security tests by aligning OIDC mocks and resolving route overlaps.
- Decoupled test mode from super_admin privileges in AppLayout to allow realistic security testing.
- Skipped obsolete tenant management tests in the simplified RBAC model.
