Both stats and policy make NMS calls that depend on bandwidth control being enabled, so move enable/disable into NMS and drop calls when disabled. This avoids throwing heavy ISE exceptions when disabled. Only include recent data when writing NetworkStatsHistory as part of dumpsys call. Introduce manual poll event for Settings UI.
