Hardware coverage: flag models the server has no drivers or BIOS for

WinPE now reports each machine's WMI model, manufacturer, Dell system
SKU and BIOS version to /hardware/seen (winpe-status-push.ps1, best
effort, wmic only). The webapp records every model seen and checks it
against what the server has:
  - each image's Deploy/Control/HardwareDriver.json, matched exactly as
    PESetup's GetDriverByModel does (as reimplemented in
    lint-driver-catalogue.py), plus whether the pack's zip is on disk;
  - the WinPE BIOS manifest (substring match like check-bios.cmd).

/hardware lists every model with per-image driver status and BIOS
status. A model missing a Win11 pack or a BIOS entry becomes item 5 on
the Technician To-Do (and the banner count) until the pack/BIOS is added
or it is dismissed. Virtual machines are ignored.

Also deploys the repo winpe-status-push.ps1 over the live copy, which
predated the -CurrentStage/-StageIndex parameters startnet.cmd passes
for the BIOS-flash stage, so that status post was failing.
