chore: remote models error handling

[louis-menlo]

Describe Your Changes

This press release aims to enhance the error handling of remote models, which previously returned a generic error message indicating something was wrong. Now, it displays a more detailed error message from the provider.

It was also an additional request that caused the confusion, so I removed it.

This also fixed Cohere & O1 models stream mode issue

Fixes Issues

• bug: [Cohere] Command-R Model Not Found Error #4054
• [UI updates] Add tabs to model selection #3475

Changes made

1. sse.ts:

   • The error handling logic was modified to check for an additional data.message field when constructing error messages. This change ensures the error message falls back to data.message if data.error?.message is not available.

2. ErrorMessage/index.tsx:

   • The ErrorCode.Unknown case was removed from the error title handling, meaning no specific title is provided for unknown errors.
   • Minor refactoring within the default case to wrap the content in a <p> tag for better semantic HTML.
   • Styled the <div> containing the error message with a centering and maximum width using classes mx-auto and max-w-[700px].

3. EventHandler.tsx:

   • An additional condition was added to the error message handling logic, checking whether the activeModelRef.current.engine is local using isLocalEngine method. This conditional change aims to ensure that only errors related to local engines trigger the following asynchronous operation.

These updates improve error handling, layout styling, and specific conditional checks in error scenarios.
