fix: wire quest progress tracking for transfer, daily, trivia, and exam events

These domain events were only connected to dashboard recording but never
called questService.handleEvent(), so quests with triggers TRANSFER_OUT,
DAILY_REWARD, TRIVIA_WIN, and EXAM_REWARD never tracked progress. Added
userId and tx to event payloads and switched from emit to emitAsync for
transaction atomicity.
