fix: resolve image display issues after refactor

- Fix upload folder path to be relative to Flask app static folder
- Update app initialization to use proper static folder structure
- Change default development port to 5001 to avoid AirPlay conflicts
- Images now display correctly in both public and admin views

The refactored app now properly serves uploaded images from the
correct static file location.
