Jason 4708700723 fix(middleware): return proper content format when no images viewed (#1454) ...

- Fix OpenAI BadRequestError: 'No images have been viewed.' was returned as
  a plain string array instead of a properly formatted content block
- The OpenAI API expects message content to be either a string or an array
  of objects with 'type' field, not an array of plain strings
- Changed return from ['No images have been viewed.'] to
  [{'type': 'text', 'text': 'No images have been viewed.'}]

Fixes #1441
