feat(b07): 안 연 측점 횡단배수 미리 넣음 — 파이썬 짝 (260-4)

- 새 B07_DesignDetail_Engine_Cad_CulvertNote = TS culvertNoteEntities · stationNoLabel 짝(두 파일 머리 표시)
- 횡단 장 만들 때 CAD 칸 없음 · 옛 글 없음 · 배수관 주인 측점 = 정본 pipe_points 로 미리 넣음 칸을 얹은 사본
- 지운 칸(빈 엔티티) · 옛 글 · 설계 없음 · 이웃 측점 = 그대로
- 시험 test_260_note_cad 거울 9쌍(같은 입력 → 같은 엔티티) · 정본 읽기 · B07 그림
