State of H1: Observing at 154Mpc

Following the power supply replacement at EX earlier tonight, Oli and I were able to recover H1 and run an initial alignment (only ETMX needed some adjustment). Lock acquisition afterwards went without issue and fully automatically and H1 began observing as of 08:16 UTC.

One thing that needed attention after rebooting the EX frontends is a restart of the ALS_XARM Guardian to reinitialize its awg connections; something we've encountered before after frontends are rebooted. I also restarted PEM_MAG_INJ and ESD_EXC_ETMX while I was at it, as I think these are the only nodes that need an awg connection to EX.
