Why It's Good For The Game

The Brig Medical APC giving power alarms every round on IceBox was annoying as hell to AIs.
The scrubber/vents can now use the Warden's office and Security office to fix air problems there without having to leave weird doors or windoors jacked open to other places for air supply.

(I did NOT put any on on the bridge because the bridge just feels, to me, like it's supposed to be sketchy, precarious, and prone to problems. Nothing but R-glass to each side and below you separating you from a swim in the plasma lake, and all that.)

Changelog

🆑
qol: Added vent/scrubber pair to the Icebox security entryway and the warden's backdoor to the armory.

It will not directly conflict with the tiles changed in the aforementioned PR, but it's likely that there may be a lurking key change that has to be forced by someone (tends to happen even if someone touches tiles on the exact polar opposite position of the same map). Depending on the order-of-operations on how we merge the PRs, it'll likely just have to be a merge conflict resolution to handle the key change rather than have to remap stuff entirely. Merge Conflicts are easy when you have git hooks, and if you manage to get sniped by one, please let me know on Discord so I can help you figure that out (tends to be hard the first time around).
