shopfloor: instrument 09-Setup-CMM, Common, Heattreat with Send-PxeStatus

Wires the imaging-progress helper into the three PC-type setup scripts
that were either clean (CMM) or untracked (Common, Heattreat). Each
gains two calls per the pattern committed for Keyence in 9122b28:

  * idx 5/8 - "09-Setup-<Type>: starting" right after the session start banner
  * idx 6/8 - "09-Setup-<Type>: complete" just before the completion banner

Display, Genspect, and WaxAndTrace also got the same two-line additions
locally and on the live server, but those files have pre-existing WIP
edits intermixed so they aren't staged here. They'll travel along
when the operator commits their unrelated shopfloor work.
