Add owner-only “I was correct” override for private multiplayer rooms

[Copilot]

Private multiplayer rooms now support an owner moderation override to mark a player’s most recent tossup ruling as correct. This enables post-ruling correction without exposing the control in public rooms.

• Owner-only private-room action

  • Added an “I was correct” action to each non-owner player entry in the multiplayer player-list dropdown.
  • Action is shown only when the viewer is the room owner and the room is private.

• Server-side correctness override flow

  • Added a new multiplayer message type: mark-tossup-answer-correct.
  • Enforced guardrails before applying override:
    • room must be private
    • caller must be room owner
    • target player must exist
    • current state must be tossup + answer revealed
    • target must match previousTossup.userId
    • previous ruling must currently be incorrect
    • no active buzz in progress
  • Applies stat corrections for the target player (points, neg/zero rollback, correct-buzz bucket, correct celerity recompute).
  • In tossup+bonus rooms, restores bonus eligibility to the corrected player’s team.
  • Broadcasts mark-tossup-answer-correct for client UI/state sync.

• Client-side sync and UI update

  • Added handler for mark-tossup-answer-correct to:
    • log moderation event in room history
    • apply stat delta in local room state
    • refresh/sort player list display
    • keep bonus-eligibility state aligned when provided by server

// server message dispatch
case 'mark-tossup-answer-correct':
  return this.markTossupAnswerCorrect({ userId, username }, message);

// owner action payload
socket.send(JSON.stringify({
  type: 'mark-tossup-answer-correct',
  targetId: userId,
  targetUsername: username
}));
