Replace YouTube cards with embedded video players

- Convert YouTube tutorial cards to embedded iframe players
- Create reusable YouTubeEmbed component in /snippets/
- Follow existing component pattern (like VersionBadge)
- Use Mintlify-compatible JSX syntax (camelCase attributes)
- Add responsive styling for better viewing experience

This improves maintainability and ensures consistent YouTube embed styling across the docs.
