feat: 数据管线 P2 优化 — 血缘写入 + 质量监控 + 缓存清理 + 重试 worker

P2-1: DataLineage 血缘写入(bzzoiro/understat Bronze→Silver 全链路)
P2-2: DataQualityCheck 质量检查写入(行计数异常检测)
P2-3: RateLimitedClient 集成到 bzzoiro 采集
P2-4: injuries 缓存过期清理(启动时扫描删除 >1h 文件)
P2-5: IngestFailure 重试 worker(FastAPI startup 注册)

新增文件:
  - src/data/retry_worker.py (死信表重试 sweep)

-## 页面说明
-
-### 1. 仪表盘 (`/admin`)
-- 系统健康状态概览
-- 联赛 / 比赛 / 预测数量统计
-- 最近联赛列表
-- 快捷操作导航
-
-### 2. 数据采集 (`/admin/collection`)
-- 选择数据源: Bzzoiro / Understat / Injuries
-- 选择联赛、日期范围
-- 触发采集任务
-- 实时任务进度显示(每 5 秒自动刷新)
-
-### 3. 预测管理 (`/admin/predictions`)
-- 触发预测(选择比赛 + 模式)
-- 模式切换: 五路专家 / 单一模型
-- 预测历史列表
-
-### 4. 回测管理 (`/admin/backtest`)
-- 回测配置: 联赛、日期范围、场数、模式
-- 回测结果: 准确率、已评分数
-- 模型评估统计
-
-### 5. 监控面板 (`/admin/monitoring`)
-- 系统健康状态(服务 + 检查项)
-- 版本与运行时间
-
-### 6. 数据源管理 (`/admin/data-sources`) ✨ 新增
-- 数据源状态: API Key 配置状态(脱敏)
-- 测试连接: 调用采集 API 验证
-- 数据源说明文档
-
-### 7. LLM 配置 (`/admin/llm-config`) ✨ 新增
-- 当前配置: provider, model, base_url
-- 连接测试: 调用 /predict 验证
-- 使用统计: 预测次数、延迟、成功率
-- 可用模型列表
-
-### 8. 系统配置 (`/admin/config`) 🔧 增强
-- 配置列表: 脱敏显示所有 .env 配置项
-- 配置修改指南: SSH 修改 .env + 重启服务
-- 快速导航: 数据源 / LLM 配置页面

-## 响应式布局
-
-### 移动端 (< 768px)
-- 侧边栏折叠为汉堡菜单,点击展开
-- 表格隐藏,显示卡片视图
-- 表单单列布局
-- 按钮最小 44px 触摸目标
-- 统计卡片 1 列
-
-### 平板 (768px - 1024px)
-- 侧边栏可折叠
-- 部分表格可用
-- 统计卡片 2 列
-
-### 桌面 (> 1024px)
-- 侧边栏固定显示
-- 完整表格视图
-- 统计卡片 4 列
-
-## 技术实现
-
-- **路由**: `react-router-dom` v6 嵌套路由
-- **样式**: Tailwind CSS 暗色主题 (gray-900/800/700)
-- **API**: 统一 fetch 客户端,30s 超时,类型安全
-- **类型**: TypeScript strict mode,与后端 Pydantic 模型对齐
-- **错误处理**: ApiError 类 + 页面级错误展示
-- **响应式**: Tailwind 断点 (sm:, md:, lg:, xl:)
-- **触摸友好**: 所有按钮 min-h-[44px]
-- **移动端**: 可折叠侧边栏 + 卡片视图替代表格
-
-## 启动方式
-
-```bash
