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)
