[Feature] support canopy chat --no-rag flag with Azure OpenAI

[orcaman]

Is this a new bug?

• I believe this is a new bug
• I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

All of my Azure OpenAI env vars are set, and I was able to both canopy upsert and canopy start using the Azure OpenAI setup.

When running canopy chat, everything works as expected.

However when running canopy chat --no-rag, after submitting the first prompt, an error is returned: "Error: No OpenAI API key provided. When using the --no-rag flag You will need to have a valid OpenAI API key. Please set the OPENAI_API_KEY environment variable."

Expected Behavior

The expected behavior is that the --no-rag flag would work for the Azure OpenAI setup.

Steps To Reproduce

1. Setup Azure OpenAI env vars
2. Run server (canopy start)
3. Execute canopy chat --no-rag

@orcaman this is currently not supported, canopy chat --no-rag is currently working with OpenAI only.

I changed this issue to a feature request.
