HAM2 Analog camera work, Maintenance 12/24

I transitioned the LVEA to Laser Hazard after lockloss, and when H1 was relocked and in OFFLOAD_DRMI_ASC, I refocused the HAM2 East door analog camera, with Corey's help in the CR, and transitioned the LVEA back to Laser Safe.  The current lens on the camera has exactly the right field of view, but a very tight focus, and there was very little light to work with at 2W, so the result is that focus moved away from the aperture of the AOE2, which is the aperture I wish to have in focus.   Next Maintenance that where it's possible to have Laser Hazard, I'll swap the lens.

Relocking was paused in OFFLOAD_DRMI_ASC for a total of 25 minutes, which was camera time and time to transition the LVEA back to Laser Safe.
