## Summary by CodeRabbit
* **New Features**
* Added an Apple Business Manager invalid-token warning banner that
lists the affected organization names.
* Introduced dedicated invalid-token state support so the banner can
appear with the correct priority.
* **Bug Fixes**
* Ensured invalid-token state is cleared when no tokens are returned and
consistently set on token fetch success/error.
* Improved Apple/DEP status messaging and made profile-assignment
rendering more resilient for non-DEP and partial-error responses.
* **Style**
* Adjusted banner spacing and added styling for DEP error presentation.
* **Tests**
* Added/expanded tests for invalid-token messaging, ABM expiry updates,
and MDM status/error scenarios.
