Subject: [PATCH] fix(policy): use container-compatible imports (drop app.
 prefix)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

프로덕션 컨테이너는 /app 을 cwd 로 실행하고 import 는 `from api...`,
`from core...`, `from workers...` 처럼 무접두 스타일을 사용한다.
PR-A 내부 import 가 `from app.policy...`, `from app.ai.envelope` 로
되어 있어서 컨테이너에서 ModuleNotFoundError 발생.

변경:
- app/policy/*.py: `from app.policy.X` → `from policy.X`
- app/services/prompt_versions.py: lazy import 도 `from policy.prompt_render`
- app/ai/envelope.py: 영향 없음 (내부 import 없음)
- tests/policy/*.py: 모두 `from policy.X` / `from ai.envelope` 로 통일
- tests/policy/conftest.py: 로컬 pytest 용 sys.path.insert(app/) 추가
  (MacBook 에서 repo-root 기준 실행 시 app/ 를 package root 로 취급)

CI: pytest tests/policy/ -q → 98 passed (로컬, 동일 결과)
프로덕션: docker exec fastapi python -c "from policy.loader import load_policy" → OK
