feat(bearing): 교각 솔플레이트를 2026-11-06 결정으로 (짝 받침 S · 열 T · 거더 하면 고정)

받침방위각_솔플레이트검토.md §3과 시안(Version 110–113)을 따른다 (사용자 결정 2026-11-06: 시안 적용).
11-03 C안(받침높이 H 고정, h3 = H − T, S 입력)을 대체한다.
- S: 교량 전체(A1, P1 … Pn, A2) 거더 짝 받침의 z 차 / 수평거리. 없으면 교각 종단경사 입력 →
  다른 열 같은 순번 값(가정, WS03) → 0 %(WS03). 받침별 직접 수정(수정됨)
- 평면 L = A + 100, W = B + 100 (받침별 A × B, 기본 700 × 640 가정), h3 181
- T = 열마다 max(22, ⌈22 + L·|S|/2⌉), 열 T 직접 수정 가능(T2 < T_min → WS02).
  T1은 오르막 쪽(3D 쐐기의 두꺼운 끝도 그쪽), T2 반대쪽
- 거더 하면 고정: 블럭 상면 = z − (T − T_ref), T_ref 30
- 짝 받침은 불러오기·프로젝트 열기 때 교량 전체로 계산해 교각 생성에 넘김
- ② 카드: h3·T_ref·T_min·여유·열 T·종단경사 입력, 표에 짝 받침·S 근거·받침별 S/A/B 수정·검산 W08·검사
- P1 검증(A1과 함께): S −1.908 … −1.902 %, L 800 · W 740 · T 30 · T1 38 · T2 22, 블럭 높이 변화 없음
- 블럭·솔플레이트 테스트는 A1–P1 짝 문맥으로 실행 (짝이 없으면 S 0 · T 22 · 블럭 +8 mm)
교대(QA-15 C안)와 Pier 시트 종단경사 열 읽기는 아직 남음.
