Add Part Marker + HeatTreat shopfloor PC types (eDNC + vendor MSI)

New gea-shopfloor-partmarker type (startnet menu option 10) and fill the
gea-shopfloor-heattreat stub. Both follow the collections eDNC pattern:
01-eDNC.ps1 installs DNC, then a 02-Setup script installs the vendor MSI.

Part Marker (02-Setup-PartMarker.ps1):
- msiexec Mark-6.2.1.msi /qn /norestart LAUNCHNTLARS=false (the LaunchNtlars
  custom action otherwise fires under /qn and launches NTLARS mid-install,
  same as eDNC).
- After install: import WJPRT.reg rewritten to WOW6432Node (reg import does
  not honor /reg:32; DNC is 32-bit and reads the redirected hive), then copy
  the Mark overlay + eMxInfo.txt into C:\Program Files (x86)\Mark.

HeatTreat (02-Setup-HeatTreat.ps1):
- msiexec HeatTreat_6.2.1.msi /qn /norestart LAUNCHNTLARS=false. Existing
  09-Setup-Heattreat.ps1 (OpenText) still runs after. Optional .reg/file
  copy left as a marked TODO pending confirmation.

Both MSIs decompiled: WiX/GE Aviation, no forced reboot, only LaunchCondition
is NOT NEWERVERSIONDETECTED. utilpassword.txt is gitignored (secret, deployed
via the enrollment share from the working tree).
