- POST /api/email/invite: sends the invite email via the Twilio Emails API using
server-only TWILIO_ACCOUNT_SID/TWILIO_AUTH_TOKEN (Vercel env), from
EMAIL_FROM_ADDRESS (default support@lynkedup.dev). Fixed invite template; gated
on a session cookie so it isn't an open relay.
- Team Management emails the invite on create and resend (token now returned by
both), with the Copy-link as a fallback. Mock mode skips email.
