Fix Bootstrap 5 modal compatibility in admin user editor

Fix "Illegal invocation" JavaScript error when opening edit modal:
- Remove Bootstrap 2 'hide' class from modal markup
- Add proper Bootstrap 5 modal structure (modal-dialog/modal-content)
- Update JavaScript to use Bootstrap 5 Modal API
- Load dynamic content into .modal-content instead of root modal
- Remove legacy data-toggle attribute from button

The modal now uses the correct Bootstrap 5.3 structure and API,
resolving selector-engine.js errors.
