feat(EventDailyStats): 添加日期选择功能，与 MarketOverviewBanner 联动

- EventDailyStats 添加日期选择器，点击日期文字弹出选择器
- 使用 Redux 共享 effectivenessStats 数据，避免重复请求
- 两个组件日期同步联动
- 仅选择今天时启用自动刷新（60秒）
- 修复 useColorModeValue Hook 规则违规（DynamicNewsEventCard、CompactEventCard）
- 添加 createSelector 优化 Redux 选择器
- 删除 EventStatsContext（被 Redux 替代）
