Fix DeviceProvisioned on PhoneStatusBarPolicy

With the new DeviceProvisionedController, adding the callback does not
immediately call it back. Instead, we need to retrieve the value on
subscription. This was causing the alarm icon not to show in QS headers
(it's blocked in other surfaces using a blocklist).

Keep it disabled (using ignore) for regular headers, but do not ignore
it in the combined headers.
