#4: scheduled meetings can now invite people who aren't on Connect.
- SMTP config (config.js, env-gated: SMTP_HOST/PORT/USER/PASS/FROM/SECURE,
PUBLIC_BASE_URL) + a small nodemailer wrapper (mailer.js) with a branded
meeting-invite template carrying the guest join link. No-op until SMTP is set.
- /api/meetings/schedule + /update accept participantEmails; external emails are
persisted (scheduled_meetings.guest_emails migration) and emailed the guest
link (plus any invited Connect users with an email on file). Fire-and-forget —
a mail outage never fails scheduling.
- Meetings list DTO returns `link`; schedule form gains an "Invite by email"
chip input; each scheduled-meeting card gets a "Copy link" action.
