받침 중심 정렬 + 부재별 색상 구분

Browse Source 
bearing.rs: X 중심, Y 하방향 (-h to 0) 기하학 수정
bridge_scene.rs: 받침 X 오프셋 제거 (girder 정렬)
Mesh: colors 필드 추가 + recolor() 메서드
sweep.rs / occt.rs: 기본 콘크리트 색 자동 채움
bridge_scene: 부재별 색상 (거더/슬래브/받침/교대)
shader.wgsl: base_color 입력 → 조명 계산에 적용

선택(Selection) 기능은 계획대로 별도 Sprint에 구현.
