Mark a conversation for QA review
Raises a review flag on a conversation the caller can already see — a rep on their own conversation, a manager on any. One open flag per conversation; flagging again returns the existing open flag. A pending flag is visible to managers and to the flagger, never surfaced to the rep until a verdict is given.
