feat: 管理界面优化 — 移动端自适应 + 数据源 + LLM 配置

移动端自适应:
- AdminLayout: 汉堡菜单 + 可折叠侧边栏 + 遮罩层 + ESC 关闭
- 所有页面响应式布局 (grid-cols-1 sm:grid-cols-2 lg:grid-cols-4)
- 触摸友好按钮 (min-h-[44px])
- 表格移动端卡片视图

新增页面:
- DataSources: 数据源状态 + API Key 脱敏 + 测试连接
- LLMConfig: LLM 配置 + 测试连接 + 使用统计 + 最近预测

增强功能:
- Config: 配置列表 + 修改指南 + 快捷导航
- types: 新增 DataSourceStatus, LLMUsageStats 等类型
- dal: 新增 testDataSource, fetchDataSourceStatuses, testLLMConnection 等

+
+## 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
+
+## 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 |

+
+## 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
+cd /vol2/1000/Docker/Profeto/frontend
+npm run dev
+# 访问 http://localhost:5173/admin
+```
+
+## 访问入口
+
+主站页面顶部「管理后台」链接可跳转至 `/admin`。
+Admin 后台左侧底栏「返回前台」链接可回到 `/`。
