修复(chat): 新增真实 IP 获取中间件及重构用户 IP 轨迹追踪逻辑

- 新增 CloudflareProxies 前置中间件，强制解析 CDN 透传的 CF-Connecting-IP 与 X-Real-IP 并在底层接管，修复 Nginx 代理造成的全局 IP 同化 (127.0.0.1) 问题
- 修改 User 模型，新增 migration 以补全真正的 previous_ip 储存通道
- 修改 AuthController 登录逻辑，在覆写 last_ip 前实现向 previous_ip 的自动历史快照备份
- 修改 UserController API 返回逻辑，实现 first_ip、last_ip（上次）以及 login_ip（本次）的三轨分离
- 更新 user-actions.blade.php 管理员视野面板，同步增加并校验“首次IP”、“上次IP”、“本次IP”三级字段映射的准确性
