"""624-4 화면 — 예정노선 지형 칩 라이다 · LAS 올리기(요구 530 · 531).

· 칩 = 예정노선 지형 칸(`UI_LidarUpload`)이 만듦 · 공용 칩 안 그대로 · 지도는 넘겨받기만
· 라이다 없음 = 「라이다」 숨기고 [LAS 올리기](부품 단추 · 파일 고르기) · 진행 = 위치 칸 서클 하나
· 고른 원천 = 세션 등록부 `d03-terrain`(draft · project) · 겹 급경사 · 음영 · 0차곡 = `terrain=` · 높이 = 원천 격자
· 원천 바뀜 = 지형 겹 셋만 비우고 다시
