feat: 添加市场截止时间筛选功能

后端：
- 为 copy_trading 表添加 max_market_end_date 字段（毫秒时间戳）
- 为 markets 表添加 end_date 字段，迁移时清空已有数据
- 实现市场截止时间过滤逻辑（仅跟单截止时间小于设置时间的订单）
- 更新 CopyTradingService 支持 maxMarketEndDate 的创建和更新
- 更新 FilterResult 添加 FAILED_MARKET_END_DATE 状态
- 更新 CopyOrderTrackingService 传递 marketEndDate 参数

前端：
- 添加市场截止时间筛选 UI（支持小时和天两种单位）
- 输入限制：仅支持整数输入（precision=0）
- 更新 AddModal 和 EditModal 支持市场截止时间配置
- 更新过滤类型显示映射（MARKET_END_DATE）
- 添加多语言支持（中文、英文、繁体中文）

数据库迁移：
- V22: 合并添加 max_market_end_date 和 end_date 字段
- 迁移时清空 markets 表数据，确保所有数据都包含 end_date
