Let people in
Admission is the act that turns an entry into an account somebody can use: it attaches the password they parked at sign-up and mails them the link that proves their address and signs them in.
Turning waitlist mode off does not do this, and the separation is deliberate — the people already in line would otherwise be left holding a password that never attached, and would find out at the login screen.
Idempotent: an entry already admitted is skipped, so a second call mails nothing.
