feat: add quality filter to Explore page

- Filter out low-quality configs (Default with generic description)
- Require either install_count > 0 OR (custom name + description + 5+ packages)
- Add secondary sorting: installs DESC + updated_at DESC for better UX
- Keep all user data intact, filter only at API query level
- Improves Explore page quality from 5/16 to 6/6 high-quality configs
