TCS SDFs and TEST_NOTIFY ignored by IFO node to get us to Observing

Reverted TCSY power head offset, was set to -17 reverted back to -15.

Reverted the channels in the screenshot related to ITMY HWS. I'm not entirely sure what these should be, but reverted for now should work until I can look into them further tomorrow.

I also added the TEST_NOTIFY node to the IFO node's exclude list. This wasn't an issue before because we have to specifically tell this node to check for new nodes, but we did a h1guardian1 reboot last week that pulled this node in.

The HWS_ORGIN_X/Y channels are used in the HWS spherical power calculation and should be centered on the IFO beam, checked in 80148. The other HWS_BEAM/CO2/RH_POS channels aren't used for anything currently, but we had ideas of using them to monitor the location of the center of the RH, IFO beam and CO2 beam.  They probably got reset tot he default values when the ITMY HWS computer crashed and IOC was restarted 80841.  For all of these, reverting was correct.

Changed the LASER POWER head offset when we re-calibrated it in 80812. It's such a small number that it doesn't really matter but reverted to old setpoint. Was accepted in safe, now accepted in observe too sdf.
