[Enhancement] Replace Error Dialog with Toaster Notification for Advanced Settings Error

[rahul-rocket]

Description:
The current error handling for the advanced settings step displays an intrusive error dialog box when an issue occurs. This needs to be replaced with a more user-friendly and non-intrusive toaster notification.

Tasks:

1. Replace the error dialog with a toaster notification.
2. Provide a more human-readable error message:

• Current Message: "You provided 'undefined' where a stream was expected. You can provide an Observable, Promise, ReadableStream, Array, AsyncIterable, or Iterable."

• Updated Message: "An unexpected error occurred while processing your request. Please make sure all required settings are properly configured."

3. Ensure that the new toaster notification styling matches the overall theme of the application.
