CMM: add PC-DMIS + combined CMM backup/restore + diagnostic scripts

Adds the PC-DMIS settings/probe backup-restore set alongside the existing
goCMM scripts, plus a single combined CMM backup and the diagnostics built
while debugging the live bays:

- Backup-PCDMISSettings / Install-PCDMISSettings: capture+restore PC-DMIS
  registry + data/probe/cal files per installed version (2016/2019/2026).
  Hardened from real-bay failures: detect install dir via Program Files
  fallback; capture compens.dat (not just comp.dat) + interfac.dll; identify
  the controller by hash-matching interfac.dll to its source DLL AND reading
  the PE OriginalFilename (covers rename-without-copy); EXCLUDE the whole
  Homepage state (Recent/Favorites/DetailsView) which null-refs PC-DMIS on
  launch via stale routine paths; restore routes HKCU into the target user's
  hive (-TargetUser ShopFloor), fails loud on a non-backup path, and applies
  the legacy->new FQDN rewrite across reg + data files incl .bas.
- Backup-CMM: one wrapper running goCMM + PC-DMIS (all versions) into one
  per-CMM folder + index, for staging on PXE and restore-by-machine-number.
- Clear-PCDMISRecent: fixes the Homepage recent-list NullReferenceException
  crash on an already-broken bay.
- pcdmis-probe-debug / Export-PCDMISCrashEvents: diagnostics for the
  custom-probe-not-showing and crash investigations.
- Modify-PCDMISRights / Grant-FullControl: grant the operator the registry +
  filesystem access PC-DMIS needs under lockdown.
- Install-goCMMSettings: add .bas to the FQDN-rewrite include list.

Not yet wired into 09-Setup-CMM auto-restore - staging + the gated restore
block come next.
