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.

- Add DomainEventPayloads interface to events.ts for typed event payloads
- Wrap dashboard listeners with fireAndForget() to prevent unhandled promise rejections
- Type all listener parameters explicitly using DomainEventPayloads
- Add idempotency guard to registerDomainEventListeners to prevent double registration on hot-reload
