fix: resolve 401 Unauthorized error in admin dashboard super admin check

- Modified check-super-admin endpoint to use requireAdminSimple instead of requireSuperAdminSimple
- Changed endpoint to gracefully handle admin authentication and return success even when super admin check fails
- Super admin functionality not fully implemented yet, so endpoint returns isSuperAdmin: false
- This prevents 401 errors while allowing admin dashboard to function properly
- Super admin button will not show but admin functionality remains intact
