The family_invites migration hasn't run yet on production. Work around by:
- Removing display_name from INSERT and SELECT (optional field anyway)
- Removing accepted_at IS NULL filter from GET and accept queries
- DELETE the invite row on accept instead of marking accepted_at — keeps
invites single-use without needing the extra column
