Monitor: 5s tight poll while DeviceId still missing

DeviceId may not be in dsregcmd output the moment Monitor starts after
PPKG reboot - takes a few minutes for AAD-join to settle. Default 30s
PollSecs leaves wide gaps where Monitor isn't checking. Sleep 5s
instead while DeviceIdReported is still false. Once captured + idx=7
push lands, falls back to PollSecs (30s) for the rest of the loop.

Worst case for QR-on-dashboard latency: ~5 seconds after dsregcmd
starts returning a DeviceId.
