feat: Add OpenAI Provider Selection

Add a provider selection dropdown to the OpenAI settings, enabling users to choose from pre-configured options like "Azure" or "Custom." This streamlines setup and allows for more flexibility in configuring OpenAI API endpoints. The dropdown pre-populates base URLs and names based on the selected provider.

The dropdown also automatically populates base URLs and names based on the selected provider, further simplifying the configuration process.
