Fixes #4816 + more

Fixes #4816 (or attempts to)
Creates proper instances of areas in engineering to prevent issues with APCs.
Removes one of the two APCs in the medbay sleeper area.

Bonus material:
Corrects a few more places where atmosphere alarms would lower shutters in adjacent but otherwise unrelated rooms.
Adds a camera at the virology entrance to remove a tiny strip of missing coverage that prevented AI from assisting people in and out from viro (perhaps intended however?).
Misc. Research (previously tele-science) had a too short power cable laid down, leaving one of the shield generators unconnected. It has been lengthened.
Port side of Security Maintenance/Prison wing had multiple turfs incorrectly designated as either space or interior. Has been sorted.
