Shows Frame.battery_percent/battery_as_of, already set by every device wake-on-battery report, plus routers/common.py's existing battery_estimate_s time-remaining estimate -- nothing new to fetch or cache. Compact (icon + percent) or detailed (+ estimate, last report age) display mode. No button actions.
