Monitor-IntuneProgress: auto-fire idx=8 on lockdown detection

Local-user shopfloor fleet (ShopFloor is a LOCAL account) means
AzureAdPrt stays NO, user-scoped Intune policies never deliver, and
the natural completion gate (baseline policies >= 5 + DSCInstall
success + Phase 4 wrappers) never closes. Dashboard sessions stuck
at 7/8 / 87.5% forever even though the bay is functionally complete.

Real-world definition of "done" for these bays is lockdown applied.
Add a per-tick check in Get-Phase1 (alongside the DeviceId push) that
detects either:
  * Winlogon DefaultUserName -like 'ShopFloor*' AND AutoAdminLogon=1
  * OR C:\Enrollment\force-lockdown-applied.txt marker file

When either is present and not yet pushed, fire Send-PxeStatus
StageIndex=8 / StageTotal=8 / Status='succeeded' with the captured
IntuneDeviceId for the dashboard QR. One-shot per session via the
LockdownCompletePushed cache flag.

No need for the operator to run mark-complete.bat anymore -
Monitor's main loop will fire idx=8 within ~5s of force-lockdown
or autologon flip.
