redesigned homepage with GSAP scroll sections and fixed mobile services carousel snap

Added new scroll-based sections (Hero, Filosofia, Approccio, BeforeAfter, CTA) with GSAP ScrollTrigger animations. Fixed mobile carousel in ServicesSection: cards now snap correctly to one-per-swipe and dot indicators track accurately. Added ScrollProgressDots component and useGsapScrollTrigger hook.
