UDC's per-bay archive directory is C:\ProgramData\UDC\ArchivedData, not
ArchiveData. The previous spelling was a typo introduced when the scripts
were first written; it would have meant Backup-UDCData.ps1 found no archive
content (silent zero-file backups), and Restore-UDCData.ps1 wrote into a
location UDC does not read from.
Path swap is straight string replacement across both scripts plus the .bat
wrapper's usage comment. Manifest field names in backup.manifest.json /
restore.manifest.json (ArchivedDataPresent, ArchivedDataFiles,
ArchivedDataBytes) updated to match.
Update-MachineNumber.ps1's parallel UDC-restore branch (still uncommitted
in a prior workstream) has the same fix in the working tree, captured in
that branch's eventual commit.
The v2 share-staged copy at tsgwp00525-v2\standard-machine\scripts\
Restore-UDCData.ps1 also got the fix and is ready for push.
