 So why wouldn't the rules book specify that the umpire is responsible for calling incorrect server violations?

 Determining proper alignment of players on the serving team at the moment of serve is specifically the Referee's responsibility - see 5-3-2-c-7. I would assume that an incorrect server would fall under this provision.
Personally, I think's it the umpire's responsibility in this situation to assist the referee by bringing it to his/her attention so they can then make the ruling.
