PostPpkg settle 60s -> 120s

Empirical: a fresh-imaged bay often hasn't finished AAD-join + first
Intune sync by 60s, so the post-PPKG-reboot Monitor instance starts
without DeviceId visible to dsregcmd yet. Doubling the settle to 120s
gives MDM more time to land baseline policies before the reboot,
which means the post-reboot Monitor sees AAD-joined + DeviceId on
first tick and fires idx=7 immediately.
