## Summary by CodeRabbit
* **New Features**
* UI now disables actions for users outside an admin’s full scope,
showing tooltips; column config now respects the current user.
* Added a permission helper to determine if one user can manage all
teams of another.
* Server-side authorization tightened to deny team-admin actions when
coverage of the target’s teams is incomplete.
* **Tests**
* Added comprehensive tests for multi-team and mixed-role permission
scenarios.
