fix: admin 比价记录列表兼容 user_id 为空的孤儿行

软鉴权/匿名下 pricebot 帧0 建行时 user_id 可空(见 models.comparison),admin
全看含孤儿行;但 AdminComparisonListItem.user_id 声明为必填 int,Pydantic v2
对 None 抛 ValidationError,致 GET /admin/api/comparison-records 列表接口 500。
改为 int|None(详情接口继承一并修复),并补回归测试
test_comparison_records_list_tolerates_orphan_null_user。
