fix(netlify): Make database connection lazy and enable serverless deployment

- Changed db.ts to use lazy initialization pattern to prevent build-time errors
- Removed static export mode from next.config.ts to support API routes
- Build now succeeds even when DATABASE_URL is not set during build time
