[bug] Add new account in incognito mode fails

[haf]

Summary

1. codex-multi-auth login
2. manual/incognito copy url to firefox https://auth.openai.com/oauth/author...
3. log in
4. copy return url: http://localhost:1455/auth/callback?code=ac_u...
5. paste into terminal; get error Login failed: OAuth state mismatch. That callback URL was generated for a different login attempt. Restart login and paste the callback URL from this attempt. - expected it to use the authz code instead of failing
