injection is prevented (using placeholders for values in statements), JS
inline code is prevented especially for url redirects, and untrusted

## Summary by CodeRabbit
* **New Features**
* Automatic macOS managed-local-account password rotation (5‑minute
scheduler) with queued SetAutoAdminPassword device commands
* Manual rotation API: POST /hosts/{id}/managed_local_account/rotate
(returns 204)
* API now reports auto-rotation timing and pending-rotation state
(auto_rotate_at, pending_rotation)
* Activity records for successful and failed rotations
* **Behavior Changes**
* Password availability is based on stored encrypted password (broader
than before)
* Rotate-while-in-flight is rejected to prevent duplicate rotations
* **Tests**
* New unit and integration tests for rotation flows, cron behavior, and
failure paths
