feat(now-playing): Love Radio через api.loveradio.ru (ICY шлёт мусор onlinestop56k)

ICY-потоки Love Radio отдают 'onlinestop56k' вместо трека. Берём текущий трек из
их API (player/history/list?musicStreamId=N&limit=1, data[0]). Статичный маппинг
наших станций -> musicStreamId. ICY-поллер исключает genre='Love Radio'.
