feat(adminfront): implement user role management and cleanup tenant list UI

- Add user role management (view, edit, bulk) in UserListPage, UserDetailPage, and UserCreatePage.
- Restrict role modification to super_admin only.
- Remove redundant action columns from tenant-related lists (TenantListPage, TenantSubTenantsPage, TenantUsersPage, TenantAdminsAndOwnersTab).
- Improve navigation by making table rows clickable where actions were removed.
