SQZ_ANG_ADJUST Guardian now controls SQZ Angle Servo, SQZ_MANAGER nominal back to FREQ_DEP_SQZ

Naoki, Sheila, Camilla

Sheila/Dave created a new SQZ_ANG_ADJUST guardian yetserday 74454 and today Naoki and I moved the ADJUST_SQZ_ANG_ADF and ADJUST_SQZ_ANG_DITHER states that were added to SQZ_MANAGER in 74428 to it, graph attached.

Now SQZ_MANAGER's nominal is set back to FREQ_DEP_SQZ and within this state, SQZ_ANG_ADJUST is requested to it's nominal ADJUST_SQZ_ANG_ADF as long as sqzparams.use_sqz_angle_adjust = True.

Nothing should be different in the working of the system apart from the nominal guardian states, tagging OpsInfo.

We had to restart SQZ_MANAGER as we deleted some of it's states, I tried to request SQZ_READY_IFO before reopening the medm and actually requested ALIGN_HD which offloaded ZC5,6 ASC and took the ZMs, FCs and PSAMs to Homodyne settings. After reverting these and SQZ FC green locked so alignment should be fine.
