feat: 完成仪表盘和导出功能

- DashboardController: 实现完整的后端API
  - /api/dashboard - 仪表盘数据
  - /api/dashboard/kpis - KPI统计
  - /api/dashboard/activities - 活动摘要
  - /api/dashboard/todos - 待办事项
  - /api/dashboard/export - 导出CSV
  - /api/dashboard/kpis/export - KPI导出
  - /api/dashboard/activities/export - 活动导出

- dashboard.ts: 前端服务
  - 完整的API调用封装
  - 导出功能支持
  - 下载工具函数

- 更新任务状态:
  - TASK-401-405: 仪表盘模块100%
  - TASK-501-502: 单元测试
