Sprint 25/26 — 단면 분기 수정 + 다경간 + 피어 배치

Browse Source 
Sprint 25: build_selectable_scene 의 SectionType::PscI 하드코딩 제거.
- p.section_type 에 따라 PscI / SteelBox 분기 (build_bridge_scene 과 동일 로직).
- 사용자가 단면 형식 전환 시 정상 반영.

Sprint 26: 다경간 + 교각 배치 (ParaWiki 교각 wiki Phase 1 MVP).
- SceneParams: span_count (1~5) + pier_type (SingleColumn/MultiColumn) 추가.
- span_m 의미 변경: 전체 교량 길이 → 경간당 길이. total = span_m × span_count.
- pier_ir_for_params() helper: 기본 사각 기둥·2m CSB·2.5m TB·5m column_height.
- build_bridge_scene / build_selectable_scene:
  · 거더: 경간마다 독립 세트 (span_count × girder_count 개)
  · 데크 슬래브: 전 구간 연속 1개
  · 받침: 모든 지점 (교대 2 + 교각 span_count-1)
  · 교각: 내부 지점 span_count-1 개 (새 기능)
  · 교대: 양 끝 (z=-800, z=total_mm)
  · 가로보: 경간마다 반복
  · 신축이음: 모든 지점 (선택적)
- build_background_scene + scene_extents: total_mm 기준으로 ground·alignment 길이 확장.
- project_file: version=2, span_count·pier_type 필드 추가 (v1 호환 default 값).
- UI ribbon: "경간 수" 슬라이더 + "교각 형식" T/π 선택.
