- getUserIdsForApartment가 apartmentName을 기준으로 동작하도록 관련 레포/서비스 정비
  (apartment.repo, auth.repo, auth.service 에 헬퍼 함수 추가)
- 공지 생성 시 주민 전체 알림 전송 로직 보강
  (전송 실패 시 개별 ignore, Promise.allSettled 적용)
- Poll Activate/Expire 핸들러 알림 전송에 try/catch 적용 및 best-effort 전송으로 변경
- Poll Activate/Expire 통합 테스트에서 pollId 기준 SSE 필터링 로직 추가
  (다른 테스트의 타이머·잔여 call 간섭 제거)
- notifications 테스트의 mock 유저 충돌 해결 및 겹치는 fixture 정리
- 전체 SSE 호출 흐름 정합성 재검증 및 안정화
