feat(bearing): 솔플레이트 표에 '방위각 검사 (″)' 열 (Q-SH4)

교각·교대 솔플레이트 상세 TABLE에 받침별로 엑셀 방위각과 짝 받침 방향의 차이(초)를 보인다.
10″ 이하 "≤ 10″", 넘으면 WS01, 짝이 없으면 "— (짝 없음)".
- BearingSole.azimuthCheckSec (짝의 from/to 쪽에 맞는 값), 표 행 azimuthSec
- 테스트: P1 전열 ≤ 0.5″ · 후열 없음, A1 ≤ 0.5″, P1 ③ 방위각 75°59′ 오타 → 약 87″ · WS01 그 받침만
- 브라우저 확인(운곡교 완도·광주 데이터): P1-광주 전열 짝 A1-광주 0.0–0.3″, 후열 짝 P2-광주 0.0–0.1″
