Add local ADB web remote for Android TV

Node/Express server shells out to adb (connect/pair/keyevent/text/app launch) and serves a mobile-first installable PWA remote: power, mute, input switch, volume/channel rockers, D-pad, media transport, text entry, and one-tap streaming app launch. Supports multiple saved TVs and the Android 11+ wireless-debugging pairing flow.
