fix: aday klibi olmayan segmentlerde neden hiçbir şey olmadığı belirsizdi

UI yenilemesinde segments/page.tsx'teki "aday klip bulunamadı" boş-durum
mesajı kanal detay sayfasına taşınmamıştı — sinyal analizi bir segmentte
ilginç an bulamayınca panelde sessizce hiçbir şey görünmüyordu, bozukmuş
gibi duruyordu.
