for more information.
- [x] Input data is properly validated, `SELECT *` is avoided, SQL
injection is prevented (using placeholders for values in statements), JS
inline code is prevented especially for url redirects, and untrusted
data interpolated into shell scripts/commands is validated against shell

## Summary by CodeRabbit
* **New Features**
* Added support for Apple declarative management declarations on both
System and User channels.
* User-scoped declarations are now delivered, reconciled, and
acknowledged independently from device-scoped declarations.
* **Bug Fixes**
* Prevented scope-mixing so declaration items and status updates no
longer affect the wrong channel.
* Tightened reconciliation behavior for scope changes and missing user
channels.
* **Tests**
* Expanded coverage for channel isolation, payload scope
parsing/validation, and correct delivery payload behavior (including
stripping the payload-scope field from delivered JSON).
