fix: add type safety and error handling to event bus

Browse Source 
- 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
