Root cause of 'stuck on downloading' bug (Android 13+):
DownloadManager.ACTION_DOWNLOAD_COMPLETE is sent by the system process,
which is external to our app. Registering the receiver with
RECEIVER_NOT_EXPORTED silently drops the broadcast — the BroadcastReceiver
never fires, the install never starts, and the UI stays frozen at
whatever progress percentage the poller last saw.
Fix: use RECEIVER_EXPORTED for the DownloadManager completion receiver in
both kiosk and scale-gateway apps.
The PackageInstaller result receiver (internal PendingIntent broadcast,
same package) correctly keeps RECEIVER_NOT_EXPORTED — that one is
intentionally app-private.
