I fixed the bug on excitation check code for commissioning break.
(Not affect for during observation runs.)
Fixed results are already available on https://gwdet.icrr.u-tokyo.ac.jp/~controls/misc/html/validation_o4break.html.

-----
OBSERVING ensures no_excitation except from pcals.
So during observing run, excitation checks were implemented as logical AND of OBSERVING and excitation bits on pcal models of both ends.

I had used same code for O4 break by using LOCKED/UNLOCKED criterion instead of OBSERVING/Non-OBSERVING criterion.
Because LOCKED state didn't ensure no excitation, operation above cannot check absence/presence of excitations in correctly.
So the code was updated to check excitation bits on *ALL* models during non-observing run period.
