fix: 优化回测功能UI和修复问题

## 主要修改

### UI 优化
- 将回测功能移到跟单交易菜单下作为子菜单
- 创建回测改为使用 Modal 方式（移除独立页面）
- 优化导航路径，使用 useNavigate 替代 window.location.href

### 功能修复
- 修复 API 路径问题：移除重复的 /api 前缀（/api/backtest -> /backtest）
- 修复 copyRatio 输入框单位：改为百分比输入（100 表示 100%），与跟单配置保持一致
- 修复回测列表中 leader 列显示为空的问题：优先显示 leaderName，为空时显示 leaderAddress

### 多语言完善
- 补充缺失的多语言 key：
  - common.ascending / common.descending / common.day
  - backtest.sortBy / backtest.sortOrder / backtest.createdAt
  - backtest.copyRatioTooltip / backtest.copyRatioPlaceholder
  - 以及其他表单验证相关的 key
- 为中文简体、中文繁体、英文三种语言都添加了完整的翻译

## 修改的文件
- frontend/src/App.tsx - 移除 BacktestCreate 路由
- frontend/src/components/Layout.tsx - 调整菜单结构
- frontend/src/pages/BacktestList.tsx - Modal 创建、修复 leader 显示
- frontend/src/pages/BacktestDetail.tsx - 优化导航
- frontend/src/pages/BacktestCreate.tsx - 同步 copyRatio 修改
- frontend/src/services/api.ts - 修复 API 路径
- frontend/src/locales/* - 补充多语言配置
