"""Sign-up codes and email sign-in codes, gone.

Both were the app doing an identity provider's job. Sign-in is through
sso.pedshub.com now: it takes the email, sends the code, checks it, and knows
about second factors — none of which this app should be reimplementing, and
two of which it never did.

invite_codes held three rows, all of them spent or stale; login_codes held
none. The dump taken beside this change has both if anybody ever wants to know
who was invited.
