- Fix Dockerfile standalone build path from /app/.next/standalone/gitea/portfolio to /app/.next/standalone/app
- Fix nginx configuration by removing conflicting server blocks
- Consolidate health check and main proxy into single server block
- Ensure proper load balancing between portfolio-app-1 and portfolio-app-2

✅ Deployment now working successfully with:
- Application running on both instances (healthy)
- Database and Redis running (healthy)
- Nginx load balancer working
- Health endpoints accessible
- Main portfolio site accessible at http://localhost/
