Email a sign-in code

POST 
/v1/auth/code

Emails a short numeric code to the address. Always responds 200 with the same body whether or not the address has an account, so it never leaks existence. A first-time address gets an account on its first successful verification, so this is both sign-up and log-in. Issuing a code invalidates any previous one for the same address.

If the address can receive a code, one has been sent.
