feat(view): ③ screen follows the 시안 — table columns, basis badges, alert buttons

- 철근표 columns as in the 시안: 구분 · 번호 · 규격 · 간격 · 실간격 · 위치 · 방향 ·
  형상 · 길이 · 개수 · 근거 · 비고. Metadata per bar from the rebar documents.
- 근거 badges: 입력 / 기본값 / 계산 / 가정 (the 가정 badge is italic amber).
- 번호 click highlights that row.
- 알림: [보기] opens the member tab; I02 [입력] focuses the fck input.
- Member tabs show the warning count.
- 공통 설정 moved to the right column (알림 → 검토 필요 → 공통 설정), as in the 시안.
- The 시안's "fck를 입력해야 생성" blocker is not used: the defaults are assumed
  values (I02), as decided on 2026-10-22.
- Not in this step: the drawings and the 정면·단면 연동 (시안 도면 뷰어).
- Not verified in a browser.
