feat: 数据采集管线基础设施接线 + 数据管线管理页

后端: - bzzoiro 采集成功后写入 RawEvent(Bronze 层原始事件存档) - 采集失败写入 IngestFailure(死信队列,支持重试) - 写入 DataLineage(ETL 血缘追踪) - 新增 DataQualityScheduler(每小时自动质量检查) - 新增 /api/v1/admin/data-quality 端点(质量检查 + 手动触发) - 新增 /api/v1/admin/ingest-failures 端点(失败记录 + 重试) - 新增 /admin/llm/ping 端点(LLM 连通性测试,不依赖比赛) - lifespan 启动 quality_scheduler 前端: - 新增「数据管线」管理页(/admin/data-pipeline) - 采集失败记录列表(状态/重试次数/错误类型) - 数据质量检查结果(通过/未通过/严重度) - 手动触发质量检查按钮 - 失败记录重试按钮 - 预测历史:比赛信息内嵌(日期/队名/主客徽标/赛果自动填充) - 导航统一为 React Router Link - AdminStats 类型扩展(matches/stats/standings 真实计数) Co-Authored-By: new-provider/LongCat-2.0 <<EMAIL>>
