martbost 08f7a408e3 Passwordless sign-in: 6-digit email codes, feature-flagged on SendGrid key
/api/auth/email/start issues a 15-min code (60s resend guard, 6 tries);
verify creates the account passwordless (sponsor cookie first-touch) and
mints the session. UI swaps the password cards for the code flow when
config.emailAuth is on; dev mode returns the code inline. Password flow
remains until the key lands in the volume (data/sendgrid.key) or
SENDGRID_KEY env.
