Outage recovery: SUS restored to top mass OSEM pointing before power outage

After restoring SUS sliders (91065), I've now gone through and restored the pointing for the top mass OSEMs for every* suspension back to where they were yesterday before the outage (around 2026/07/16 04:11:58 UTC) (NOT back to where they were during last DRMI lock since we have since changed the alignment when doing our backwards alignment for the BS). Most didn't have to move much / at all but a few did have to move quite a bit on the sliders. Suspensions that have OPLEVs, I referenced those as well, and those all lined up with addressing the top level suspension alignment. All changed alignment offset values were accepted into SDF.

* A few suspensions where I did not restore pointing to where they were yesterday are ZM4 and ZM5 since I know those are actively being worked on and I didn't want to mess up any alignments from earlier today.
