OpenAI requests fail with "Unsupported parameter: 'reasoning_effort' is not supported with this model"

[Akhundoff]

What happened?

When using ProxyAI in PhpStorm with an OpenAI API token, requests fail with the following error:

Unsupported parameter: 'reasoning_effort' is not supported with this model

This happens in at least two places:

1. Generating commit messages
2. Selecting a code block and asking a question about it

The OpenAI token is successfully saved in the plugin settings, but actual requests fail.
