TV episode rows show runtime; channel video cards showed nothing per video. The
InnerTube lockup already carries both — now we capture duration ('12:34') + an
approximate view count (parsed from '2.6M views') in innertube_parse_video_items,
remember them on youtube_channel_videos (new duration/view_count cols + migration),
and render a duration badge bottom-right of the thumb + 'N views' in the card meta.
The background stream backfills them onto the recent (yt-dlp) videos too, so the
whole catalog gets them. Live-validated (MrBeast: 32:08 / 50M, 30/30). 65 tests green.
