 * M02_MasterTemplete_Labor_RowModal.ts
 * 일위대가표 줄 누름 모달(PLAN 723-2 · 요구서_내역16 2장 4) — 일위대가표에서 빠진 줄 동작을 모달 안으로.
 *  · 로직 줄 · 단가산출(SK) 참조 줄 = 머리(이름 · 「1 ㎡ 당」) · [옵션 · 메모](`Labor_Input` · 켜쌓기율) ·
 *    로직 자재(바꾸기 · 기본 · 세 칸 · `Labor_LogicMats`) · [단가산출 보기](717-3 `Labor_SangeunModal`)
 *  · 사용자 자재 줄 = 자재 모달(세 칸 · `Labor_MatTable` 한 줄)
 *  · 고침 = 그 줄 화면 캐시(저장은 [저장]) · 금액은 표가 다시 셈 → `watch` 로 받아 다시 그림
