Older API keys not supported #6133
Description
What version of Codex is running?

What subscription do you have?
None (API key)
Which model were you using?
gpt-5-codex
What platform is your computer?
WSL2 - ubuntu 24.04
What issue are you seeing?
I was trying to use an API key generated in Oct 2024, but kept getting retry timeouts (421 not authorized). But I know the key works for other requests.
The only way I could get it to work was to generate a new key with the same permissions ("all") as the old one.
What steps can reproduce the bug?
Use a key generated from a year ago that looks roughly like this
sk-qW0XXXXXXXXXXXXXXXm
/logout from within Codex, and then launch codex and login with your api key. (Confirm it got entered correctly at ~/.codex/auth.json.
Then codex e test and get Retry 5/5 421 unauthorized (forgot to grab the actual text but that's the gist of it).
Then do the same with a new key of the format below
sk-proj-XXXXXXXXXXXXXXXXXXXXXXXXX-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXx7MA```
And get the expected behavior of a working codex prompt.
