Summary: v0 adds Folders UI and Supabase templates

Why It Matters: The platform is expanding its library of ready-made building blocks. This helps developers start complex projects like file management systems or database-connected apps faster.

What Changed:

• Added a new "Folders UI" template to the featured list.
• Added a "Supabase Community Starter" template for database integration.
• Added an "Artist Portfolio" and "Marketing Website" to the homepage gallery.
• Updated the view counts and usage stats for most existing templates.
• Removed several older template previews from the bottom "Ship mobile sites" section.
