OPS OWL report SDF diffs

To get in Observing I had to accept some SDF diffs for SQZ, and PCALY. There was also still a PEM CS excitation point open as well. There was a notification about PCALY OFS servo malfunction so I looked at it and it was railed at -7.83, so I toggled it off and back on and it brought it back to a good value. I also did not receive a call, a voicemail just appeared.

09:21 UTC observing

H1:SQZ-LO_SERVO_IN1GAIN was left at -15 by accident, reverted to -12 and saved in sdf.

SDF diffs for PCALY were incorrect. The timing of these changes match the h1iscey reboot done the same day (82902). Today around 19:00 UTC (almost three weeks later), we used EPICS values from the Pcal calibration update done in September (80220) to revert changes. Saved changes in OBSERVE and SAFE.
