[MAP] Extends medbay vertically two tiles, adds bolt buttons to toilet stalls

- Extends cloning lab, cryogenics room, sleeper room and surgery by two tiles to try to ease the amount of shoving during emergencies (e.g. blob, nuke ops, virus outbreak, alien invasion). It's very frustrating trying to cryo and sleeper and clone and perform surgery with a bunch of patients and volunteers all pushing and shoving in the currently tiny areas. Hopefully these two extra tiles vertically will make it easier.

- Adds bolt buttons to toilet stalls so players can AFK, spawn traitor items or absorb genomes in there in peace. Also for fluff, as public toilets have locks.
