Register touch_scroll_panel::<HelpScrollable> so the Controls overlay can be scrolled by swipe on Android. Without it, the Mode Launcher and Overlays sections (rows 2–19) were unreachable via touch. Also add 96px bottom padding to HelpScrollable — same fix applied to settings_plugin — so the last row clears the scroll-container edge. Register TouchInput message so existing headless tests continue to pass. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
