Separate CookieList template rendering from consent modal design

Hi, thank you for allowing to configure the Fluid templates! We encountered a new problem when setting a custom path for the Cookie list template:

plugin.tx_sgcookieoptin {
    settings {
        templates.CookieList.full = EXT:sitepackage/Resources/Private/Templates/Extensions/sg_cookie_optin/CookieList/Full/
    }
}

The custom path will currently only be used if template_selection in the consent record is set to "full".

This connects the rendering of the cookie list with the styling of the consent modal.

Is the following condition in CookieListController and LegacyOptinController still necessary or a remnant of the former rendering?

if ($optin['template_selection'] === 1) {
    $templatePath = $this->settings['templates']['CookieList']['full'];
    $templateRootPaths = $this->view->getRenderingContext()->getTemplatePaths()->getTemplateRootPaths();
    $templateRootPaths[0] = $templatePath;
    $this->view->setTemplateRootPaths($templateRootPaths);
}
