 * NetworkConnection
 *

 * 
 * Usage:
 * ```qml
 * import qs.utils
 * 
 * // With Session object (controlcenter)
 * NetworkConnection.handleConnect(network, session);
 * 
 * // Without Session object (bar popouts) - provide password dialog callback
 * NetworkConnection.handleConnect(network, null, (network) => {
 *     // Show password dialog
 *     root.passwordNetwork = network;
 *     root.showPasswordDialog = true;
 * });
 * ```
