[manual] Add User fields to the UserProfile model.

And keep the fields updated, by copying on UserProfile creation and
updating the UserProfile object whenever we're updating the User
object, and add management commands to (1) initially ensure that they
match and (2) check that they still match (aka that the updating code
is working).

The copy_user_to_userprofile migration needs to be run after this is
deployed to prod.
