- Admin invites by entering email instead of copying a link
- If email matches existing Tia user → creates pending invite visible
on their Circles page with Accept/Decline buttons
- If email is not registered → sends Resend email with signup link
that lands them directly in the circle after account creation
- DB migration adds invited_email + invited_family_id to circle_invites
- New GET /api/circles/invites endpoint for pending invite banners
- Remove clipboard-copy approach entirely
