feat(approvals): 결재 접근 차단 대응과 전표 전이 메모 전달 강화

- approvals 모듈에서 APPROVAL_ACCESS_DENIED 응답을 포착하여 ApprovalAccessDeniedException으로 변환하고 접근 거부 시 토스트·대시보드 리다이렉트를 처리

- approval history 조회가 서버 action id에 맞춰 필터링되도록 repository·controller·테스트를 보강

- 재고 트랜잭션 상태 전이 API 호출에 note를 전달하도록 repository·컨트롤러·통합/단위 테스트를 업데이트

- 승인 플로우 QA 체크리스트 및 연동 문서를 최신 계약과 테스트 흐름으로 업데이트
