Set OpenAI ApiVersion to empty on initialization

Set OpenAI ApiVersion to be empty during initialization; otherwise the Ruby-Openai gem will force v1 in the URL

Hi @papayalabs. This worked fine for my setup with OpenAI, Anthropic, Ollama, and Groq.
Although I had to manually add v1/ to the OpenAI API Services setting. I think you could safely add a migration to update any record that matches https://api.openai.com/ exactly.

Ready @mattlindsey! Thanks for the recommendation.
