feat: Simulate now on

[lee-to]

You can render system pages that need a resource and a page in the URL on arbitrary routes by simulating their URLs

class HomeController extends Controller
{
    public function __invoke(FormArticlePage $page, ArticleResource $resource)
    {
        return $page->simulateRoute($page, $resource)->loaded();
    }
}

NowOn also improved

HasMany::make('Comments', resource: CommentResource::class)
    ->creatable()
    ->nowOn($resource->getFormPage(), $resource, ['resourceItem' => $item->getKey()])
    ->fillCast($item, new ModelCaster(Article::class)),
