CMM: wire per-bay settings restore into the imaging flow

Restore-CMM.ps1 (new) restores a CMM's PC-DMIS + goCMM settings at imaging from
its staged backup. Self-gating: reads C:\Enrollment\cmm\{cmmid,version,doda,
partgroup}.txt, skips DODA bays and bays with no staged backup, and restores
ONLY the config-version PC-DMIS zip via the existing Install-*Settings scripts.
Same-bay restore (cmmid match) so the backed-up controller CommPort is this
bay's own value - no cross-bay clobber.

Version selection matches the VERSION FIELD of the zip name, anchored on the
trailing timestamp, so version=2026 does not false-match a 2019/2016 zip whose
backup timestamp (20260612...) merely contains "2026".

09-Setup-CMM.ps1: new Step 2.8 calls Restore-CMM after app install + first-run
init (so a restored config is not clobbered by PC-DMIS defaults) and before the
C:\CMM-Install cleanup (the backup set lives under <stagingRoot>\backups\<cmmid>).
Best-effort: Restore-CMM always exits 0, imaging never fails on a restore.

startnet.cmd: stage ONLY the picked bay's backup into C:\CMM-Install\backups\
%CMMID% (the bulk robocopy now /XD-excludes the backups tree, which holds every
bay's backup - some 240 MB each - to avoid copying GBs to every imaged CMM).
Also bump the PPKG to v4.16 (the live boot.wim was already v4.16; the repo had
drifted to v4.14).

sync-cmm-backups.sh: source the backups from pxe-images/cmm/backups (where
Backup-CMM writes via the pulled-down copies), not the old cmm-bk path.

Smoke tested on the win11 VM against CMM3's real backup: version=2019 restored
the 2019 R2 zip (not 2016.0), imported HKLM+HKCU reg, converted the part-group
S:\ path to the tsgwp00525 UNC, created C:\geaofi, exit 0; version=2026 correctly
found no matching zip (anchor works).
