"""272-1 측점 한 벌 — 화면(TS)과 서버(파이썬)가 같은 측점 목록을 냄(요구 167 · 측점 겹침 근본).

- 심는 자리: TS `plantedChainages` ↔ 서버 `resolve_extra_stations`(관 · 독립 기슭막이 시작 ·
  기준 · 끝 · A군 · C군 구간형 시작 · 기준 · 끝 · 물넘이포장 기준(286-1) · 다른 군 · 점형 C/D 는 안 심음).
- 같은 m = 측점 하나 · 구조물이 위 · 떠나면 일반 측점: TS `oneStationList` ↔ 서버
  `_merge_irregular_into_longitudinal`.
진짜 TS 는 `helper_272_1_station_list.cjs` 가 Node 로 돌림.
