"""Round 11 四轮 — chatgpt.com session_token 注入到 personal OAuth 跳过 /log-in.

阻塞场景:
- 刚被 master kick 出 Team 的子号在 OAuth /log-in 页 fill email 后,Continue 按钮变灰禁用,
  login flow 永远卡在 email 步骤,bundle=None。
- 5 次外层重试全失败,W-I9 / 二轮 / 三轮 修复都救不回来。

修复路径(本测试文件覆盖):
1. `_register_direct_once` 注册成功前从 chatgpt.com BrowserContext 抽
   `__Secure-next-auth.session-token` (含 chunked .0 / .1) 并返回 (success, session_token)。
2. `create_account_direct` 把 session_token 透给 `_run_post_register_oauth`。
3. `_run_post_register_oauth` 把 session_token 透给 `login_codex_via_browser`。
4. `login_codex_via_browser` 在 use_personal=True + session_token 时,把 cookie 注入
   `auth.openai.com`,/oauth/authorize 看到有效 session 直接跳过 /log-in。

参考:`SessionCodexAuthFlow._inject_auth_cookies`(主号专用 cookie 注入模式),
本轮把模式扩展给 personal 子号。
