for more information.
- [x] Input data is properly validated, `SELECT *` is avoided, SQL
injection is prevented (using placeholders for values in statements), JS

## Summary by CodeRabbit
## Summary by CodeRabbit
* **New Features**
* Apple declarative management now supports asset-backed declarations,
including device delivery of referenced DDM assets.
* Added a new device-facing endpoint to fetch managed DDM assets by
identifier (scoped to the device’s team).
* **Bug Fixes**
* Declaration/profile updates now refresh when referenced assets change
(not just variables).
* Device and host token/declaration matching now accounts for asset
update timing to trigger redeploys reliably.
* Improved validation to detect missing/invalid asset references before
saving.
* **Other**
* Updated which configuration declaration types are blocked during
user-provided validation.
