 * B09_Estimation_UI_Haul_Modal.ts
 * 「운반 단가」 모달(PLAN 253-3 · 263-1 · 요구 162-1 · 164-1) — 운반공 줄 하나(거리이정표 행 하나)의 단가연결.
 *   위 = 고른 항목 이름 · [변경](단가연결 한 목록 `openPriceLink` — 단가산출 · 사전조합 · 구조물 조합 · 호표) ·
 *   왼 = 고른 항목이 요구하는 입력만(단가산출 = 로직 입력 `fetchLogicInputs` · 호표 = 입력 없음) ·
 *   오른 = 계산 절차 — 거리 줄 · 사이클 식 줄(TS 짝 `B08_Quantity_Haul_Cycle` · 8-2-8 기본값 · 거리 칸 있을 때만) +
 *     로직 산출 줄(서버 `POST …/estimation/logic-preview` · 값 바꾸면 다시 · 최신 응답만).
 *   거리 칸(운반거리 · Cm · 사이클시간 · t2) = 거리에서 채움(「거리에서」) · 손으로 고치면 덮음(`own`) ·
 *   빈칸으로 지우면 다시 거리에서. 옛 사이클 손 값(`cycle`) = 칸 없음 · [적용]하면 지움(기본값).
 *   연결 없는 줄도 같은 모달(빈칸 → [고르기]) · [적용] = 부르는 쪽 `apply`(캐시 → [저장] 때 서버 정본).
 *   여는 곳 = B08 거리이정표 표 우클릭 · B09 설계내역서 운반공 줄 단가연결.
