Fix empty Swagger UI: drop invalid presets/layout config

SwaggerUIBundle.presets.apisAndSaver does not exist (undefined), which broke
initialization and rendered nothing. Use the minimal canonical config (url,
dom_id, deepLinking, persistAuthorization) and drop the now-unused standalone
preset script.
