Refactor SSE response handling and display

Updated response body widgets to handle SSE output as a list of strings instead of a single string. Adjusted view options for SSE-related media types and refactored SSEDisplay to be a stateless widget that accepts a list of SSE events. This improves clarity and consistency in handling and displaying SSE responses.
