feat: 修复订单查询和物流查询功能

主要修改：

1. 订单数据解析修复 (agent/agents/order.py)
   - 修复 Mall API 返回数据的嵌套结构解析
   - 更新字段映射：orderId→order_id, orderProduct→items, statusText→status_text
   - 支持多种商品图片字段：image, pic, thumb, productImg
   - 添加详细的调试日志

2. 物流查询修复 (mcp_servers/order_mcp/server.py)
   - 修复物流接口返回数据结构解析 (data[].trackingCode→tracking_number)
   - 添加 print() 日志用于调试
   - 支持多种字段名映射

3. Chatwoot 集成优化 (agent/integrations/chatwoot.py)
   - 添加 json 模块导入
   - 完善订单卡片和表单展示功能

4. API 请求头优化 (mcp_servers/shared/mall_client.py)
   - 更新 User-Agent 和 Accept 头
   - 修正 Origin 和 Referer 大小写
