Reorganize frontend into public/ with pages/ and js/ subdirectories

- public/index.html — landing page at root
- public/pages/ — all feature pages (regulations, loadboard, etc.)
- public/js/ — api.js, nav.js, mock data files
- All links updated to absolute paths (/pages/, /js/)
- Express static path updated to serve from public/
- Seed script path updated for new mock data location
- README updated with new project structure and setup guide
- Added .env.example template
