B 站首页 header 新旧两套实现并行灰度，登录入口选择器不同：
- 新版 header：.header-avatar-unlogin-entry
- 旧版 header：.right-entry__outside.go-login-btn 内的 .header-login-entry

原代码只匹配旧版，且 header 版本按 cookie 分流（携带过期 SESSDATA 也会
被分到新版），导致未登录场景下点击登录按钮直接 30s 超时。

改为组合选择器，并在等待超时时输出明确的排查提示，替代原先裸的
Playwright traceback。两套 header 的按钮均调用同一个 openMiniLogin()，
弹窗及二维码结构未变，故无需改动。
