Subject: [PATCH] fix: align backend port to 3000 across all configurations

The production docker-compose used port 3000 internally but nginx.conf
was hardcoded to port 3001, causing 502 errors on the root path (/).

Changes:
- Update nginx.conf to use backend:3000
- Update docker-compose.yml to use PORT=3000 for consistency
- Update port mapping and healthcheck to use port 3000
