fix(abut): 교대 받침 공통 규칙을 교각 솔플레이트 규칙 형식으로 변경

- 이전 가정(받침 A×B 700×640, h3 181, T 30, 여유 100)을 없애고, 교각과 같은 솔플레이트 규칙(src/core/solplate-rule.ts)을 씀 (결정 2026-11-03: 교각 규칙을 기본값으로)
- 입력: 솔플레이트 교직 L 1000, 교축 W 1100, 종단 기울기 S −0.5 %. 받침높이 H는 교대 받침 시트 값(A1 275 mm)으로 고정
- 계산: T = ⌈22 + L·|S|/200⌉ = 25, h3 = H − T = 250, T1 27.5 / T2 22.5, E = 400. 교각 카드와 같은 안내 줄 표시
- 받침 종류 · 용량 입력은 유지. ELEVATION TABLE의 A·B 열 삭제, 삽도는 솔플레이트 L × W 기준
- 테스트 갱신. 전체 651건 통과, 타입 검사·빌드 통과. 브라우저 시각 확인은 미실시
