CommentResponse has author_id (UUID, nullable) but no author name or email.
Frontend impact (found while building #88): comments can show body + timestamp
but not who wrote them — only a UUID is available. Need author name/email on
the response for a usable comment thread.
Same family as #86 (MemberResponse missing email). Out of frontend lane —
filing so it's tracked.
