fix: resolve CI test failures in ChatbotEnhanced and ReportViewer

- ChatbotEnhanced: replace deprecated `className` prop on ReactMarkdown v10
  with a wrapping div element
- ReportViewer test: update assertion to match actual component output
  (individual "PDF" button instead of non-existent "Export" button)
