Pull request overview
This PR updates the fallback model ID for completions from gpt-4o-copilot to gpt-41-copilot to align with changes observed in the CLS (Copilot Language Service). This is a straightforward constant update that affects the default model used when no other model is available or configured.

@jeffreyhunter77 It seems to break one of the chat-lib tests. Could you take a look?

We noticed in the CLS that the fallback model id was still
gpt-4o-copilotand we're updating it togpt-41-copilot. This makes the same change for completions from the chat extension and chat-lib.
