codex --model accepts any model name and codex will report it is using it

What version of Codex is running?

v0.1.2505172129

Which model were you using?

I don't know and that is the problem

What platform is your computer?

Linux 6.8.0-45-generic x86_64 x86_64

What steps can reproduce the bug?

I should say that I am using azure so maybe that is my issue.

$ codex --provider AZURE --model crazy-obviously-fake-model-name

What is the expected behavior?

Announce the requested model is unavailable and either state it's using a fallback or just refuse to proceed
Should report the actual model it is using
