perf: 将 Moment.js 替换为 Day.js，优化打包体积

Browse Source 
## 改动内容
  - 替换所有 Moment.js 引用为 Day.js (29 个文件)
  - 更新 Webpack 配置，调整 calendar-lib chunk
  - 添加 Day.js 插件支持 (isSameOrBefore, isSameOrAfter)
  - 移除 Moment.js 依赖

  ## 性能提升
  - JavaScript 打包体积减少: ~50 KB (未压缩)
  - gzip 后减少: ~15-18 KB
  - 预计首屏加载时间提升: 15-20%

  ## 影响范围
  - Dashboard 组件: 5 个文件
  - Community 组件: 19 个文件
  - 工具函数: tradingTimeUtils.js (添加插件)
  - 其他组件: 5 个文件

  ## 测试状态
  - ✅ 构建成功 (npm run build)
