feat(image-lab): Dockerfile + compose entry + scripts 6위치 + nginx 차단

Task 5 of Video Studio backend plan. Wires image-lab Python code (T1-T4)
into NAS Docker infrastructure on port 18802.

- image-lab/Dockerfile (python:3.12-slim + uvicorn)
- image-lab/requirements.txt (fastapi, redis, httpx)
- image-lab/env.example (INTERNAL_API_KEY, IMAGE_DATA_DIR, REDIS_URL, CORS)
- docker-compose.yml: image-lab service block (port 18802, redis depends_on,
  healthcheck, volume ${RUNTIME_PATH}/image-data:/app/data) + frontend
  depends_on entry
- scripts/deploy-nas.sh: SERVICES += image-lab
- scripts/deploy.sh: BUILD_TARGETS/CONTAINER_NAMES/HEALTH_ENDPOINTS += image-lab,
  DATA_DIRS += image
- nginx/default.conf: /api/internal/image/ 3-layer block (IP allowlist +
  deny all + X-Internal-Key forward) mirroring /api/internal/video/

Plan-B-Video lesson: 6-location registration enforced per
feedback_nas_deploy_paths.md rule 3 to avoid 'transferring dockerfile: 2B'
deploy failure.

Tests: image-lab pytest 11 passed (no regression).
