feat(B07): 계획평면도 종류 · 정보 조각 서버 (PLAN 60-1 · 60-2)

- 정보 조각(등고선 · 계류 · 중심선 · 성토사면 외곽선 · 비탈 눈금 · IP · R · 측점 NO · 시종점 · 대피소/사토장 · 라이다 배경)마다 장별 파일(plan_pieces/{장}/{조각}.json)
- 외곽선 = 노견 끝 + 설계선이 지반에 닿는 자리(B06 횡단 설계 결과) · 측점 자리는 횡단 파일 중심 · 좌축
- 종류 = 조각 고르기 목록(plan_kinds/{id}.json) · 기본 넷(지형 · 노선배치도 · 대피소 · 라이다) · 더하기 · 지우기 API
- 대피소 · 사토장 = 구조물 정본 refuge · spoil_bank + 사용자 지정 자리(plan_marks.json)
- 도면 목록 · 단건 조회를 종류 × 장으로 · 옛 plan_* id 그대로 이어짐
