Fix is applied on the GitOps side since that's what I figured the
customer was using on the [Slack
thread](https://fleetdm.slack.com/archives/C061ZA91Y1J/p1779372669701129).

## Summary by CodeRabbit
* **Bug Fixes**
* Corrected GitOps behavior for the macOS “Update new hosts to latest”
setting so it no longer stays enabled after clearing `minimum_version`
and `deadline`; it now defaults to disabled unless both are set.
* **Tests**
* Added GitOps test coverage to verify the defaulting outcomes across
YAML variations for the macOS update settings, including explicit and
empty field combinations.
