perf(infra): NAS CPU 폭주 5건 일괄 fix (CHECK_POINT 🔴 즉시)

J4025 Celeron 2C/2.0GHz에서 oversaturation을 일으키던 5개 패턴 해소.

1) 09:00 cron 스태거링 — agent-office insta_trends 09:00 / lotto 09:05 /
   youtube 09:10, realestate-lab collect 09:15. 동시 실행 4개가 직렬
   분산되어 1분 단위로 분산됨.
2) lotto Monte Carlo 08:05 → 08:30 — stock 08:00 cron과 25분 분리.
3) insta-lab card_renderer.render_slate를 asyncio.Semaphore(1)로 감쌈.
   동시 슬레이트 렌더 요청이 와도 Chromium 인스턴스 1개만 직렬 launch.
4) docker-compose healthcheck interval 30s → 60s (9 백엔드 + frontend
   총 10개). 30초마다 동시 healthcheck로 인한 CPU 잡음 절반으로.
5) 9개 백엔드 Dockerfile CMD에 --workers 1 명시. 기본값 의존 제거.

CHECK_POINT.md 갱신 — 즉시 5건 체크 + 변경 이력 한 줄.
적용 효과 검증: NAS 재기동 후 `docker stats` 비교.
