SQZ Alignment using SQZ Single Bounce

Naoki, Vicky, Camilla, Sheila. Copied instructions from 78115.

Today we couldn't find the SQZ beam while the IFO was locked using  SQZ-OMC_TRANS_RF3_DEMOD_RFMON as we'd been ale to do in 78088. When the IFO unlocked we used the SQZ SEED beam in a SQZ single bounce (much higher power so easier to see) to  improve the SQZ alignment. Expect when we're locked will still need to touch alignment, may get away with a few rounds of SQZ_MANAGER's SCAN_ALIGNMENT_FDS state (wiki notes). Notes below.
