perf: Lenis smooth scroll ve scroll skew efektini kaldır

Site geneli ScrollFlow sarmalayıcısı (Lenis lerp'li kaydırma + hıza bağlı
skewY) tüm sayfa katmanını her karede transform'luyor, kaydırma performansını
düşürüyordu. Yerel tarayıcı kaydırmasına dönüldü; bölüm çapaları mevcut
scroll-mt değerleriyle çalışmaya devam eder. lenis bağımlılığı ve
data-lenis-prevent işaretleri temizlendi.
