imaging: renumber stages to be time-monotonic (1=WinPE, 7=Intune ID)

Previously the stage indices reflected logical milestones but not the
order they fire in. Run-ShopfloorSetup posted idx=1 (start) and idx=4
(PPKG) - but 09-Setup-Keyence (inside per-type loop) ran BETWEEN them
and posted idx=5/6. The dashboard then "regressed" from 6 back to 4
when PPKG fired, making it look stuck at the per-type-complete card.

New numbering matches actual execution order:

  1 - WinPE: PESetup / WIM apply              (startnet.cmd)
  2 - Run-ShopfloorSetup: starting            (Run-ShopfloorSetup.ps1)
  3 - 09-Setup-<Type>: starting               (per-type)
  4 - 09-Setup-<Type>: complete               (per-type)
  5 - Run-ShopfloorSetup: PPKG enrollment     (Run-ShopfloorSetup.ps1)
  6 - Run-ShopfloorSetup: handoff to Monitor  (Run-ShopfloorSetup.ps1)
  7 - Monitor-IntuneProgress: Intune Device ID captured

services/imaging_status.py rewind threshold reverts to stage_index <= 1
now that WinPE startnet posts idx=1.
