Use proper Bootstrap 5 native modal API with initialization

Bootstrap 5 removed jQuery plugin support, so .modal('show') doesn't work.
Switch back to native Bootstrap 5 Modal API with proper initialization:

- Dispose of any existing modal instance before creating new one
- Create modal with explicit options (backdrop, keyboard, focus)
- Add detailed console logging for each step

This ensures the modal is properly initialized before showing.
