feat: 添加价格区间过滤功能并优化UI

- 添加价格区间过滤功能（minPrice/maxPrice）
  - 数据库迁移：添加价格区间字段到 copy_trading 和 copy_trading_templates 表
  - 后端：实体类、DTO、服务层支持价格区间配置和过滤
  - 前端：模板和配置页面添加价格区间配置UI
  - 过滤逻辑：在订单创建前检查价格是否在配置区间内

- 优化价格区间文案，使其更易懂
  - 明确说明是 Leader 交易价格
  - 详细说明三种配置方式（区间、只填最低价、只填最高价）

- 补充多语言翻译
  - 为 zh-CN、zh-TW、en 添加价格区间相关翻译
  - 添加价格区间过滤类型翻译
  - 添加通用翻译（prev、next、items、total）

- 修复复制模板功能
  - 补充缺失的过滤条件字段（minOrderDepth、maxSpread、minOrderbookDepth、minPrice、maxPrice）
  - 在复制模板表单中添加所有过滤条件配置项

- 已过滤订单列表优化
  - 添加移动端卡片样式布局
  - 在筛选下拉菜单中添加价格区间过滤类型选项

- 订单页面返回按钮优化
  - 买入订单、卖出订单、匹配关系页面的返回按钮改为返回上一页（navigate(-1)）
  - 使用多语言支持返回按钮文本
