Fixes people shouting at AI to open unseen doors (sometimes).

Adapted previous PR for dev where cameras were relocated to allow AI to see important areas. Affects:
Virology entrance - Can now see both sides of the entrance from medbay (rather than none of them)
Medbay patient corridor - No longer loses coverage in hallway as patient rooms shutters are closed
West of AI Upload entrance - Allows sight of the HoP's door and 3 nearby public doors
East Central Primary Hallway - No longer lose coverage when the chemists close their shutters
Engineering lobby entrance - Can now see all doors in the public hallway + the maintenance entrance
Security Permabrig - Can now always see the last set of door before the permabrig.
