CMM: add backup staging (sync-cmm-backups.sh) + write cmmid.txt at resolve

Browse Source 
sync-cmm-backups.sh pushes per-CMM backup sets (goCMM + PC-DMIS zips produced
by Backup-CMM) from pxe-images/cmm-bk/<cmm_id>/ to the PXE share at
installers-post/cmm/backups/<cmm_id>/, atomic-swap with a timestamped prior
copy. Distinct from sync-cmm.sh (which stages the CMM installer bundle).

resolve-cmm-bay-config.ps1 now also writes cmmid.txt alongside version/doda/
partgroup, so 09-Setup-CMM can locate this bay's staged backup for
restore-by-machine-number.

The 09-Setup-CMM restore block + startnet staging line are intentionally NOT
added yet - the restore needs manual end-to-end validation on a real CMM
before auto-running at imaging (per the live-bay restore issues we hit).

# sync-cmm-backups.sh - stage per-CMM backups (goCMM + PC-DMIS) on the PXE
# enrollment share so 09-Setup-CMM can restore them by CMM machine-# at imaging.
# (Distinct from sync-cmm.sh, which stages the CMM *installers* bundle.)
#
# Source layout - one folder per CMM, named by the cmm_id in cmm-bay-config.csv,
# produced by Backup-CMM.ps1 and mirrored here from the live bays:
# /home/camp/pxe-images/cmm-bk/<cmm_id>/
# gocmm_backup_<PC>_<ts>.zip
# pcdmis_backup_<PC>_<ver>_<ts>.zip (one per installed PC-DMIS version)
# cmm-backup-index.json
#
# Pushes the NEWEST backup set per cmm_id to:
# /srv/samba/enrollment/installers-post/cmm/backups/<cmm_id>/
#
# DODA bays: do NOT back them up (don't put them under cmm-bk/). 09-Setup-CMM
# also gates restore on cmm-bay-config doda=no as a second guard.
#
# Usage: ./playbook/sync-cmm-backups.sh (all cmm_id folders)
# CMM_ID=CMM3 ./playbook/sync-cmm-backups.sh (just one)
