    文件功能：好友列表浮窗面板

    提供全局 JS API：
      window.openFriendPanel()   打开好友面板（自动刷新列表）
      window.closeFriendPanel()  关闭好友面板

    面板分为两个区域：
      1. 📋 我关注的好友 —— 我已添加的人，显示互相状态、添加时间、删除按钮
      2. 💌 对方已加我   —— 别人加了我但我未回加，显示对方添加时间、回加按钮

    搜索栏支持输入用户名后按 Enter 或点击「➕ 添加好友」直接添加。

    所有添加/删除操作调用与双击用户卡片完全相同的后端接口：
      POST   /friend/{username}/add
      DELETE /friend/{username}/remove

    依赖：
      - window.chatContext.roomId  当前房间 ID（由 frame.blade.php 注入）
      - meta[name="csrf-token"]   CSRF 令牌
