feat(532-5): E03 2D 해석에 벽(옹벽 · 석축) 연결 · 횡단 없는 측점 띠(E02 · E03)

- analyze2d 가 측점마다 벽(walls_by_station · 복사 지문으로 기억) · 그려지는 설계선을 넘김 · 벽 있는 측점만 지문에 벽 · 벽 없는 측점 = 종전 지문
- 측점 보기 = 같은 벽 모형 · 수위선 = E02 고른 지하수 갈래(station_groundwater)
- 화면 — 「반영 전」 안내 걷음 · 벽 회색 빗금 · 결과 「벽 있음」 · 목록 벽 표시
- result2d · stab/ground 에 missing_stations 칸 덧붙임 · 화면 위 띠(펼침 목록)
- E03 지반 조건 = E02 화면과 같은 upgrade(옛 정본 지하수 칸 기본값)
