fix: WebSocket 관련 서비스를 Singleton으로 변경

ImGdevel · ImGdevel · commit a1364dd380b6 · 2025-09-23T23:21:38.000+09:00
MessageBroker와 WebSocketManager를 Scoped에서 Singleton으로 변경
- DistributedMessageBroker의 Redis 구독 중복 방지
- 분산 환경에서 메시지 중복 처리 방지
- 프로세스 전역 상태 일관성 보장
- 자원 누수 및 성능 문제 해결

변경된 서비스:
- IMessageBroker (DistributedMessageBroker, LocalMessageBroker)
- IWebSocketManager (DistributedWebSocketManager, WebSocketManager)
