Feature: #107791 - Reports module uses native submodule overview 

Description 

The Administration > Reports module has been refactored to use TYPO3 Core’s native submodule system with the showSubmoduleOverview feature instead of a custom report registration mechanism. This provides a more consistent user experience and aligns the Reports module with other TYPO3 backend modules.

The module now displays a card-based overview of available reports, similar to other modules like the Content > Status module. Each report is registered as a proper backend submodule in Configuration/Backend/Modules.php.

Changes 

Module structure:

• Administration > Reports is now a container module with showSubmoduleOverview enabled.
• Individual reports (Status, Record Statistics) are registered as submodules.
• The native submodule overview automatically provides cards with icons, titles, and descriptions.

Benefits:

• Automatic "Module Overview" menu item in the submodule dropdown.
• Consistent navigation experience across all TYPO3 backend modules.
• Simpler architecture without custom registration infrastructure.
• Easier to extend - just add submodules to Modules.php.

Example 

Creating a custom report now follows the same mechanism as registering a backend submodule:

return [
    'system_reports_myreport' => [
        'parent' => 'system_reports',
        'access' => 'admin',
        'path' => '/module/system/reports/myreport',
        'iconIdentifier' => 'my-report-icon',
        'labels' => 'my_extension.module',
        'routes' => [
            '_default' => [
                'target' => \MyVendor\MyExtension\Controller\MyReportController::class . '::handleRequest',
            ],
        ],
    ],
];

The controller returns a standard PSR-7 response with rendered content:

use TYPO3\CMS\Core\Attribute\AsController;
use TYPO3\CMS\Backend\Template\ModuleTemplateFactory;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;

#[AsController]
final readonly class MyReportController
{
    public function __construct(
        protected ModuleTemplateFactory $moduleTemplateFactory,
    ) {}

    public function handleRequest(ServerRequestInterface $request): ResponseInterface
    {
        $view = $this->moduleTemplateFactory->create($request);
        $view->assign('data', $this->collectReportData());
        return $view->renderResponse('MyReport');
    }
}

Impact 

The Administration > Reports module now provides a cleaner and more intuitive interface using standard TYPO3 backend navigation patterns.

Extension developers can create custom reports by registering them as backend submodules, using the same module registration mechanisms already available in TYPO3, instead of implementing a separate custom report interface.
