feat(wpf): v2 - restore live thumbnail preview column in participants table

Browse source 
96x54 thumbnail (16:9) fed from the engine's most recent ProcessedFrame. Em-dash placeholder when no pipeline is running. Same pattern as v1 - lifted Image binding to Thumbnail with HasThumbnail visibility flip. Sits between the state LED and the name+codec caption.
