修复Dify对话记录加载问题：移除user参数，由后端自动管理

Browse Source 
问题描述：
- 用户登录后无法加载历史对话记录
- 根本原因：前端传递的user值与实际用户不一致，导致Dify无法找到对应的对话

解决方案：
- 后端已实现user字段自动填充功能（v1.2.7-post2）
- 前端采用方案A：完全移除user参数传递
- 让后端从JWT中自动提取username并管理user字段

修改内容：
1. dify-client.server.ts
   - 移除所有方法的user参数
   - GET请求移除user查询参数
   - POST/DELETE请求移除user字段
   - 移除generateUserId工具函数

2. 所有API路由
   - 移除getSessionInfo中的user解构
   - 移除difyClient方法调用中的user参数传递
   - 日志中移除user信息输出

影响接口：
- GET /dify/conversations - 会话列表
- GET /dify/messages - 消息历史
- POST /dify/chat-messages - 发送消息
- POST /dify/conversations/{id}/name - 重命名会话
- DELETE /dify/conversations/{id} - 删除会话
- POST /dify/messages/{id}/feedbacks - 消息反馈

参考文档：docs/dify-frontend-user-field-guide.md
