fix: canlı-tespit fetch'ine cookie ekle — AB consent duvarını aş

Coolify sunucusu AB'de; oturumsuz istek YouTube'un interaktif consent
sayfasına düşüyor (o sayfada videoDetails yok), bu da gerçekten canlı
bir kanalı "değil" gibi gösteriyordu (doğrulandı: @ertemsener canlıydı,
sistem "değil" dedi). yt-dlp için zaten sakladığımız oturum açık
cookie'leri aynı fetch'e Cookie header'ı olarak eklendi — giriş yapılmış
hesaplar consent duvarını hiç görmüyor.
