feat(B07,B08): 워크플로 순서 교환 — 상세설계를 수량산출 앞으로

횡단설계(B06) 다음을 상세설계 → 수량산출 → 설계도서 순으로 재배열하고,
폴더 번호가 흐름과 일치하도록 이름을 맞바꾼다.

- B08_DesignDetail → B07_DesignDetail, B07_Quantity → B08_Quantity
  (파일 접두어·식별자·라우트·locale 키 전량 스왑)
- STAGE_KEYS 4=DESIGN_DETAIL, 5=QUANTITY 스왑 + 라우터 stage 리터럴 교체
- CAD 마운트 /b08-cad → /b07-cad (main.py·vite proxy·iframe URL),
  openwebcad Toolbar 라벨 B07로 수정 후 재빌드
- 유지: openwebcad postMessage 프로토콜 aislo:b08:*·패키지명(내부 식별자)
- 기존 프로젝트 storage 폴더 rename + project_manifest 갱신,
  DB project_workflow_stages stage_no 4↔5 행 스왑 완료
