Answer 1

I did everything as here prestatips.info/adding-new-hook-prestashop
1. Added a hook in the database:
2. Added CategoryController.php class to override/controllers/front/

class CategoryController extends CategoryControllerCore
{
    /**
     * @see CategoryControllerCore::initContent()
     */
    public function initContent()
    {
        parent::initContent();
 
        $this->context->smarty->assign(
            'HOOK_CATEGORY_TOP', Hook::exec('displayCategoryTop')
        );
    }
}

3. Deleted the cache/class_index.php file
4. Added themes/themename/category.tpl in the view

{if $HOOK_CATEGORY_TOP}
    <div class="hook_category_top">
        {$HOOK_CATEGORY_TOP}
    </div>
{/if}

But the hook is not added to him!
