test_integration_modules.py — 17개 유틸리티 모듈 통합 테스트

task-856.1에서 생성한 유틸리티 모듈들이 dispatch.py, orchestrator.py,
chain_manager.py에 올바르게 통합되었는지 검증한다.

검증 항목:
- dispatch.py: redact, injection_guard, approval, audit_logger 통합
- orchestrator.py: config_loader, interrupt, memory_manager 통합
- chain_manager.py: atomic_write, usage_pricing 통합
- 모듈 없을 때(모크 ImportError)도 기존 동작 유지 (backward compatible)
