Improved Custom Model Integration in Chat Component

This PR enhances the custom model integration in the Chat component by:

1. Refactoring the model fetching logic to properly handle errors and display user-friendly messages
2. Adding a dedicated ChatModelError class to standardize error handling
3. Creating a new EndpointTokenSelect component to allow users to select from available endpoint tokens
4. Improving the CustomModelForm to better handle base URL and token inputs
5. Separating the model selection UI logic to only show when models are available
6. Implementing proper state management for base URL and token values

If the base path is empty, select the token and refresh, every input is initialized. But after refreshing again, Base Path has 'v1' automatically.
