ttipo f725908053 feat(backend): 실시간 알림 GET /api/mail-events (엔진 EventSource 중계)
- 직원마다 엔진 EventSource 하나를 그 직원의 연결들이 나눠 쓴다(fan-out) — state · 받은편지함 안 읽음 · 새 메일 계산은 직원마다 한 번
- 새 메일: Email/changes → Email/get 으로 받은편지함 · 초안 아님 · 안 읽음 · 본인 아님 · 10분 넘게 앞서지 않은 메일만,
  셀 수 없거나(cannotCalculateChanges · 400 notRequest) 2,000건 넘게 바뀌면 state 만 보내고 기준을 다시 잡는다
- 연결 5개 한도, 25초 ping(upstream), 토큰 만료 30초 전 end(남은 시간이 짧으면 끝날 때), 서버 종료 때 end,
  처리 전에 끊긴 응답 정리, 처음 엔진 연결 10초 상한
- 엔진 연결: 75초 무소식이면 다시 잇기(±20%), 엔진 429 는 끊지 않고 다시 묻기, 같은 기준 3번 실패면 기준 다시 잡기, 5분 안전판
- 액세스 토큰의 만료 시각을 AuthenticatedUser 에 싣는다(선택 필드), 요청이 끝난 뒤에도 이어지는 일은 요청 컨텍스트 밖에서
