Include service in Now Watching progress bar

Include the service icon, e.g. Plex, Stremio, etc., in the progress bar while you're watching something.

Perhaps this icon could also be included somewhere in the watched history as well so you know where you watched things. If it's been manually marked, or imported and doesn't contain this data, perhaps either no icon, or the We icon.
