chore: 移除 Telegram PR 合并通知工作流

- 重构 formatNumber 和 formatUSDC 函数，默认添加千分位分隔符
- 更新 Statistics.tsx、CopyTradingStatistics.tsx 等统计页面
- 更新 PositionList.tsx 持仓列表的数值显示
- 更新 AccountList.tsx 账户列表的余额显示
- 所有数值（金额、数量、价格等）现在默认显示千分位
- 示例：1234567.89 显示为 1,234,567.89

影响范围：
- 工具函数：utils/index.ts
- 统计页面：Statistics.tsx, CopyTradingStatistics.tsx
- 业务页面：PositionList.tsx, AccountList.tsx

Changes:
- Refactored formatNumber and formatUSDC to include thousand separators by default
- Updated statistics pages to display numbers with commas
- Updated position list and account list for better readability
- Example: 1234567.89 now displays as 1,234,567.89

+## ⚠️ 潜在问题和注意事项
+
+### 1. 数值格式化变更
+
+**影响**：
+- 所有数值现在默认显示千分位分隔符
+- 如果之前有代码依赖特定的数值格式，可能需要调整
+
+**建议**：
+- 检查是否有代码依赖特定的数值格式
+- 确认数值显示是否符合预期
+
+### 2. 移除maxPositionCount配置
+
+**影响**：
+- 如果之前使用了最大仓位数量限制功能，升级后将不再可用
+- 需要手动调整跟单策略

+
+---
+
+## 🔄 升级建议
+
+1. **检查数值显示**：
+   - 升级后检查所有数值显示是否符合预期
+   - 确认千分位分隔符显示正确
+
+2. **检查跟单配置**：
+   - 如果有使用最大仓位数量限制的配置，需要手动调整
+   - 确认跟单功能正常工作
+
+3. **检查Leader列表**：
+   - 升级后检查Leader列表显示是否正确
+   - 确认仓位信息是否完整
+
+4. **数据库迁移**：
+   - 升级时会自动执行数据库迁移 V26
+   - 迁移会删除 `max_position_count` 字段
+   - 建议在升级前备份数据库
