Add Multiple Carousels to Homepage & PDP

We've revamped the homepage and product page experience with a cleaner layout, faster onboarding, and full multi-carousel management.

New & Improved

• Multi-Carousel Management — Create custom carousels for both product pages and homepage. Scope carousels to specific products, manage videos through a dedicated drawer, and control whether the default carousel is visible.
• Streamlined Homepage section UX & Onboarding — Cleaner homepage section layout with direct create triggers for banners and widgets. Default naming removes setup friction so you can get started faster.
