Move logic that loads related articles in the footer to PHP from JS. This prevents us from shipping an RL module to a client and not showing related articles. Also, make sure not to load related articles in footer on Special:MobileDiff. Bug: T144047 Change-Id: I73e39ee6b1223699cd8ac739902315d163d98c3b
