 * @summary `np-status-history` is a custom element that displays the status history of a service.
 *
 * @description
 * This component connects to a WebSocket server to receive real-time updates and renders the status history accordingly.
 * It maintains a list of status updates and displays them based on the success and error counts.
 * The possible status indicators are:
 * - `operational`: All systems are functioning correctly.
 * - `disrupted`: Some errors occurred.
 * - `down`: No successful responses.
 * - `nodata`: Insufficient data to determine status.
 * - `offline`: Unable to connect to the service.
 *
 * @csspart link - The component's link wrapper.
