Fix Node.js 18 compatibility for Vercel deployment

- Switch from @neondatabase/serverless to standard 'pg' client for Node.js 18 support - Update Node.js version to 18.x as required by Vercel - Replace Neon template literals with standard parameterized queries - Add proper connection pooling and SSL configuration for production - All API endpoints updated: /api/v1/cards/, /api/v1/cards/[id], /api/migrate - Build tested and working successfully
