refactor: remove notebook implementation and update project assets

Remove the Jupyter notebook file and associated example report, update README.md to reference new images in the research/ directory and remove notebook run instructions, and refresh example query buttons in the web app with new topics. This shifts focus to the Reflex web app while cleaning up obsolete files.
