 * @brief Status bar presentation of server round-trip health.

 * Combines the textual "Ping" readout with a small LatencyGraphWidget
 * sparkline of the rolling sample window. Clicking anywhere in the area opens
 * a popup with a larger graph and the numeric statistics. It closes on any
 * outside click. Stays hidden while disconnected or before any samples exist.
 * Owns all latency display state so MainWindow only needs to forward one
 * signal here.
