HTTP 501
email_not_configured
What to do: Set RESEND_API_KEY and MAIL_FROM on the server, or create a key in the dashboard.
POST /v1/auth/request-code needs outbound email configured on this instance (self-host parity: it is optional). Until then, sign in to the dashboard and create an API key from Settings.
