feat(cc-logs-app-runtime): handle cc-logs-clear event to clear displayed logs

Wires the clear button (added in e04781b) to the app-runtime smart controller so users can
drop the currently displayed logs without interrupting the live stream. Resets the visible
log tracking alongside the component clear so overflow detection stays accurate.
