CMM: create C:\GE PC-DMIS FRONT END at imaging + move regserver helper to Public desktop

- Ensure-PCDMISFrontEnd.ps1/.bat: standalone fix for already-imaged bays -
  create C:\GE PC-DMIS FRONT END + grant Users/Auth Users Modify. PCDToIGES.exe
  writes its error log there in its catch block; on a fresh bay the dir is absent
  (legacy front-end setup isn't part of imaging), so ANY PCDToIGES error becomes
  an unhandled DirectoryNotFoundException that crashes the export and masks the
  real cause (confirmed live on a CMM bay).
- 09-Setup-CMM Step 2.5b: create that dir + ACL at imaging for every CMM bay.
- 09-Setup-CMM Step 2.5: Register-PCDMIS-COM.bat now lands on the Public desktop
  (visible to operator or SupportUser) instead of SupportUser-only.
