Dorm privacy switch and station map fixes (#17217)

* Dorm privacy switch and station map fixes

Added privacy switches to all dorm rooms, these buttons make an overlay appear on the room for ghosts preventing them seeing inside. This does not currently prevent them hearing emotes from inside the room, it's purely a visual block.

Fixed station maps for the map linter PR, still have many more to do but those are out of the scope of this PR, just wanted to tick these ones off whilst I'm editing the maps anyway.

* Also adds an air alarm to the atmos breakroom
