Tuesday afternoon DAQ restart for Beckhoff slow controls channel change

WP12980 DAQD code upgrade.

Jonathan, Daniel, Dave:

The DAQ was restarted at 16:08 Tue 27jan2026 for Beckhoff ISC-CS changes, applied when Daniel restarted the slow controls system earlier that afternoon. This was an EDC + DAQ restart.

We took this opportunity to complete the upgrade of DAQD on the 1-leg (it has been running on the 0-leg for over a week).

the 0-leg was a standard retstart, the 1-leg was a staggered restart node-by-node to implement the upgrade, followed by a full restart of the 0-leg.
