Unfollow a conversation

Unfollow a conversation
Remove a follower from this conversation. Returns 404 when no follow row exists for the (conversation_id, user_id) pair so the FE can distinguish ‘no longer following’ from ‘successfully unfollowed’. CASCADE-purge semantics: a conversation that has been hard-deleted reaps its followers via the migration-634 FK, so a stale unfollow against an already-purged conversation 404s on the row, not on the conversation.
