Enforce character limit and Latin characters in addresses

In order to mail something out through Pirate Ship, each address line has to be 35 characters or less. Additionally, mail needs to be in Latin script. As such, I think it would be a good idea to enforce this at the auth level so we don't have to end up reaching out to every person individually about fixing their address.

The issue does not name a file or test; start by locating the authentication flow that accepts and stores address fields. Confirm how address lines are represented and how Latin-script validation should behave, then verify that every address line is at most 35 characters and uses Latin characters before mailing-related account data is accepted.
