update_settings() now persists timezone_configured=True when the changes
supply timezone without timezone_configured, so Home Assistant's reported
zone can no longer replace an admin-chosen zone (release review RR-001).
An explicit timezone_configured is kept as supplied; the automatic
adoption path is unchanged and still leaves the marker false.
