/**
 * Service to triggers an app-wide auto-refresh (if enabled, on a configurable interval) via the
 * application's root RefreshContextModel.
 *
 * For this service to be active, it must be configured/enabled in two ways:
 *
 *  1) A refresh interval for the client app must be specified via the `xhAutoRefreshIntervals` JSON
 *     config. Intervals are specified in seconds and keyed by `clientAppCode` to allow for
 *     different auto-refresh behaviors across different JS apps in the same project.
 *
 *  2) The user's `xhAutoRefreshEnabled` preference must be set to true. This is currently a single
 *     pref. applied to all JS apps in the project. Apps can add an {@link AppOption} to allow users
 *     to customize via the global options dialog, or set a default pref value if per-user
 *     customization is not desirable.
