/**
* PSR-14 event that allows listeners to modify the buttons in the backend module
* document header button bar. This event is dispatched after all buttons have been
* added to the button bar, but before they are rendered.
*
* Use cases:
* - Add custom buttons to existing modules
* - Remove or hide buttons based on conditions
* - Modify button properties (labels, icons, etc.)
* - Reorder buttons
*
* Example event listener:
*
* ```
* use TYPO3\CMS\Backend\Template\Components\ModifyButtonBarEvent;
* use TYPO3\CMS\Backend\Template\Components\ButtonBar;
* use TYPO3\CMS\Backend\Template\Components\ComponentFactory;
* use TYPO3\CMS\Core\Attribute\AsEventListener;
*
* final class MyButtonBarListener
* {
* public function __construct(
* protected readonly ComponentFactory $componentFactory,
* ) {}
*
* #[AsEventListener]
* public function __invoke(ModifyButtonBarEvent $event): void
* {
* $buttons = $event->getButtons();
* $buttonBar = $event->getButtonBar();
*
* $myButton = $this->componentFactory->createLinkButton()
* ->setHref('/my-action')
* ->setTitle('My Action')
* ->setIcon($iconFactory->getIcon('actions-heart'));
*
* $buttons[ButtonBar::BUTTON_POSITION_RIGHT][1][] = clone $myButton;
*
* $event->setButtons($buttons);
* }
* }
* ```
