Imaging floor: Standard/Engineer builds report progress past WinPE

The floor's 8 stages are the shopfloor pipeline, and only shopfloor-setup
reports after WinPE, so every gea-standard / gea-engineer build sat at
1/8 forever with no type.

- winpe-status-push.ps1 reads the image from the Z: share mapping when no
  PCTYPE is set and reports those builds as 5 steps.
- Send-ImagingStage.ps1 (deployed to _shared\Applications\extra\pxe-status)
  posts steps 2-5 from the unattend: start and end of specialize, first
  logon, and setup complete (succeeded). It is copied to
  C:\ProgramData\PxeStatus first, because the bulk-enrollment task deletes
  C:\Deploy before first logon. Best-effort: always exits 0.
- Floor rows use Standard/Engineer labels and show the image as the kind.

Tested as SYSTEM in the win11 VM (PowerShell 5.1): the exact unattend
command line, stages 3-5 against a test server, a dead port (exit 0), and
the image regex.
