feat: add web frontend shells (Home panel, Project panel, API client)

- Add research_web/index.html as entry point with navigation
- Add research_web/js/api_client.js with all research API endpoints
- Add research_web/js/app.js with Home and Project panel renderers
- Add research_web/css/research.css with dark theme styling
- Add server.py static route for /research endpoint
- Add placeholder .gitkeep files for empty subdirectories
