feat(story): 完成故事016.009 - React图表组件封装

实现内容:
- 创建 BaseChart 基础组件,封装 Canvas 创建和销毁逻辑
- 创建 ColumnChart 柱状图组件
- 创建 LineChart 折线图组件
- 创建 CandleChart K线图组件
- 创建 PieChart 饼图组件
- 创建 RadarChart 雷达图组件
- 所有组件支持 Props 配置、触摸事件、响应式尺寸
- 类型检查通过(pnpm typecheck)
- 构建成功(pnpm build),生成 .d.ts 文件
- 创建基础测试,测试通过

修改文件:
- mini-ui-packages/mini-charts/src/components/*: 新增6个图表组件
- mini-ui-packages/mini-charts/src/index.ts: 添加组件导出
- mini-ui-packages/mini-testing-utils/: 添加 Canvas 相关 mock
