Implement proper Amplify Gen 2 secret management

- Create Lambda function with secret environment variable
- Add YouTube API function to backend configuration
- Create Next.js API route to handle YouTube requests
- Update gallery page to use API route
- This follows the correct Amplify Gen 2 pattern for secrets
