Standardize the calibration source. Step 3b already restores a per-asset
backup ZIP (HKLM + data + config, incl. the probe cal tables) for any bay
that has one - which is now every migrated bay. When that ZIP is staged,
skip the redundant and fragile cal-ISO mount/vendor-Setup step so all
bays follow one flow (app ISO + backup restore), matching the bays that
never had a cal ISO. A future bay with a cal ISO but no backup still
falls through to the ISO path unchanged.
