feat(now-playing): now-playing + обложки для Зайцев ФМ

19 каналов Зайцев ФМ (MP3 abs.zaycev.fm) не отдают ICY → трека не было.
ZaycevNowPlayingService (@Interval 30с): тянет текущий трек из API сайта
GET https://www.zaycev.fm/api/v1/recent?channel={slug}&limit=1 (slug = буквенная
часть имени потока, pop256k→pop), берёт artist/title и готовую обложку
(radio2.zaycev.fm/artistimages), фильтр is_music. Зайцев исключён из ICY-поллера.
