 The advertising identifier (IDFA) as an uppercase UUID string, or nil.

 Non-nil only when all of these hold: `sendIDFA:YES` was called, the device runs iOS 14.5+
 and `ATTrackingManager.trackingAuthorizationStatus` is `.authorized`, and the identifier is
 not the all-zero value. VPKit never presents the tracking prompt; the host app owns that.
 The installation UUID (`app.consumerId`) stays the primary consumer identifier.
