fix(docker): 서비스 restart 정책 보강 및 mc-observability-front nginx 프록시 추가

[dogfootman]

Summary

• docker-compose.yaml: mc-workflow-manager, mc-application-manager, mc-data-manager에 restart: unless-stopped + depends_on 추가 — 초기 기동 순서 문제 및 서버 재시작 후 미기동 현상 수정
• docker-compose.yaml: mc-observability-rabbitmq, mc-observability-influx, mc-observability-influx-2, mc-observability-loki의 restart: on-failure → restart: unless-stopped 변경 — clean exit(0) 후에도 재시작 보장
• nginx.template.conf / nginx.template.local.conf: mc-observability-front용 nginx 프록시 서버 블록 추가 (포트 MC_OBSERVABILITY_FRONT_PORT) — iframe이 HTTPS 컨텍스트에서 접근 가능하도록 SSL 종료
• api.yaml: mc-observability-fe 서비스 URL 등록 — mc-web-console Monitorings 화면에서 iframe 표시에 필요

Test plan

• ./mcc infra run 실행 후 mc-workflow-manager, mc-application-manager, mc-data-manager가 정상 기동되는지 확인
• 서버 재시작 후 위 서비스들과 observability 관련 서비스들(rabbitmq, influx, loki)이 자동 복구되는지 확인
• https://<IP>:<MC_OBSERVABILITY_FRONT_PORT>/embed/monitoring/default HTTPS 접근 확인
• mc-web-console 로그인 → Workspace/Project 선택 → Monitorings 화면에서 iframe 콘텐츠 표시 확인

AI Direct Commit Attribution Blocked

This pull request cannot be merged because it contains commits with AI tool attribution (Claude, Anthropic, GitHub Copilot, etc.) in commit message trailers (for example Co-Authored-By, Signed-off-by, Generated-By) or in the author/committer email.

Why this is blocked

In open-source contributions, the human author is expected to create commits and open pull requests. Under current open-source license frameworks (DCO, Sign-off, CLA, etc.) AI-attributed commits may have unclear implications. Following the community proposal from 2026-05-08, until the project policy is finalized, AI direct commit signoff and co-authored-by records are prohibited in this repository.

How to fix

Most recent commit only - strip the attribution trailers:

git commit --amend --message="$(git log -1 --pretty='%s%n%n%b' | grep -vE 'Co-Authored-By:|Generated-By:|Assisted-By:|Co-Developed-By:')"
git push --force-with-lease

Multiple commits - use interactive rebase:

git rebase -i HEAD~5
# Mark each commit as `reword` and remove the trailer lines in the editor
git push --force-with-lease

The check will re-run automatically after the force-push, and the merge can proceed once the AI direct commit signoff and co-authored-by records are removed. Repository administrators may also enforce this check via Branch Protection rules.
