The unit app does not register plugin blueprints, so render_template could not find _host_vitals.html or _host_metrics.html (TemplateNotFound, CI run 8384). tests/_templates.render_plugin_template renders a plugin's template through the app's own Jinja environment and request context, with the plugin's template folder ahead of the app's loader.
