Wax/Trace: switch baseline to FormTracePak v6.213 vendor install

Replace the V6.0 captured-binary replay (pf-x86-MitutoyoApp.zip +
c-MitutoyoApp.zip + hklm-wow-mitutoyo.reg.gz) with a real vendor install
from FORMTRACEPAK-V6.213.iso mounted via Mount-DiskImage.

09-Setup-WaxAndTrace.ps1:
- Step 2 rewritten: Mount-DiskImage on
  C:\WaxTrace-Install\formtracepak\FORMTRACEPAK-V6.213.iso, run the VB6
  Setup.exe wrapper from the assigned drive letter (DRIVE_CDROM check
  satisfied by virtual mount, no real CD needed), then Dismount.
- Header rewritten: drop captured/ description, note legacy fallback
  remains in the repo (captured-binary/ unchanged) for manual recovery
  if the v6.213 vendor install fails on a bay.

sync-waxtrace.sh:
- Push formtracepak/FORMTRACEPAK-V6.213.iso (2.0 GB) into the bundle
  instead of captured/ payload. Override path via $FTPAK_ISO env var if
  needed (e.g. testing a v6.213 patch ISO).
- Sanity check no longer demands pf-x86-MitutoyoApp.zip; only requires
  prereqs/ + the manifest + dispatcher PS1.

playbook/utilities/convert-cal-iso.sh:
- New helper. Rebuilds a Linux-dd of a multi-session UDF cal disc into
  a clean ISO9660+UDF hybrid that Windows Mount-DiskImage reads. mkisofs
  reads the file via loop-udf, repacks single-session with the asset tag
  as volume label. Run when `file CAL-*.iso` reports "data" (multi-session
  UDF dd produced a Linux-readable but Windows-unreadable container).
  Single-session 218-458A discs from dd are already ISO9660 and don't
  need this.

Verified on win11 VM via qga: V6.213 ISO mounts, Setup.exe locatable.
14 cal ISOs all converted to ISO9660 (md5s refreshed in INDEX.csv),
re-synced to /srv/samba/enrollment/installers-post/waxtrace/calibrations/.
PXE share bundle now 2.0 GB total (V6.213 ISO + 14 cal ISOs + prereqs).

+#!/bin/bash
+# Convert a Linux-dd multi-session UDF cal ISO into a Windows-readable
+# single-session ISO+UDF hybrid. Mounts the dd file via UDF loop, copies
+# files into a temp tree, repacks via mkisofs with ISO9660+UDF.
+#
+# Use this when a Mitutoyo cal disc was ripped with `dd if=/dev/sr0`
+# (default Linux rip). For multi-session UDF discs `dd` captures session
+# 1 only and truncates trailing UDF Anchor Volume Descriptor Pointers;
+# the file mounts on Linux (loop-udf) but Windows Mount-DiskImage reports
+# IsReady=False. mkisofs rebuilds clean metadata Windows reads. Linux
+# still reads the result.
+#
+# Single-session discs (older 218-458A Mitutoyo pattern) are already
+# ISO9660 from dd - no conversion needed. Run `file CAL-*.iso`:
+# ISO 9660 = fine; "data" = convert.
+#
+# Usage: convert-cal-iso.sh <input.iso>
+# Replaces input in place. Saves <input>.dd-backup on first run.
+#
+# Requires: sudo (loop-udf mount), mkisofs (genisoimage / cdrtools).
