feat: 后台管理 Admin 仪表盘

新增完整的后台管理系统 (/admin):
- Dashboard: 系统概览、最近采集状态、预测统计
- Collection: 数据采集触发(bzzoiro/understat/injuries)
- Predictions: 预测历史查看、触发新预测
- Backtest: 回测配置与结果查看
- Monitoring: 系统健康、错误日志、死色队列
- Config: API Key 与数据源配置

技术栈: React Router + Tailwind 暗色主题 + TypeScript
文件: 11 个新文件, +21KB JS / +5KB CSS

+## 页面说明
+
+### 1. 仪表盘 (`/admin`)
+- 数据库表行数统计
+- 最近采集任务状态
+- 预测统计(总数、今日数、平均延迟)
+- 最近错误日志
+
+### 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(全部联赛或指定联赛)
+- 模式切换: 五路专家 / 单一模型
+- 预测历史分页查看
+- 评估结算(回填实际结果)
+
+### 4. 回测管理 (`/admin/backtest`)
+- 策略选择: 置信度加权 / Kelly准则 / 固定金额
+- 联赛多选、日期范围、初始资金配置
+- 回测结果: ROI、胜率、最大回撤、夏普比率
+- 交易明细可展开查看
+
+### 5. 监控面板 (`/admin/monitoring`)
+- 系统健康状态(服务 + 检查项)
+- 错误日志(每 10 秒自动刷新)
+- 死信队列监控
+
+### 6. 配置管理 (`/admin/config`)
+- API Key 配置(LLM / 数据源 / 系统)
+- 脱敏显示 + 在线编辑
+
+## 路由设计
+
+| 路径 | 页面 | 描述 |
+|------|------|------|
+| `/` | 先知主站 | 报纸风格预测展示 |
+| `/admin` | 仪表盘 | 系统概览 |
+| `/admin/collection` | 数据采集 | 采集任务管理 |
+| `/admin/predictions` | 预测管理 | 预测与评估 |
+| `/admin/backtest` | 回测管理 | 策略回测 |
+| `/admin/monitoring` | 监控面板 | 系统监控 |
+| `/admin/config` | 配置管理 | 参数配置 |
+
+## 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
+- **自动刷新**: 采集(5s)、监控(10s)
+
+## 启动方式
+
+```bash
+cd /vol2/1000/Docker/Profeto/frontend
