 * B09_Estimation_UI_Tab_UnitPrice.ts
 * B09 일위대가 탭 — 목록표 + 일위대가표 (STmate `일위대가목록표` · `wM_Edit_iLWi` 보기 · PLAN 12장 1차)
 *
 *   - 목록표 = 내역에 쓰인 호표만, **내역에 처음 쓰인 차례**로 「제 N 호표」(번호는 서버가 낼 때마다 매김).
 *   - 줄을 누르면 아래에 그 호표의 일위대가표 — 호표 안 줄(하위 호표·단산·중기)을 누르면 더 들어감.
 *   - 구조물도 호표는 B08 구조물도 탭의 일위대가 표가 본표 — 여기선 금액·안내만.
 *   - 편집(구성행 수정)은 2차 — B09 에 수정 저장 자리가 아직 없음(브레인 판정).
