fix: nginx container build

[araujof]

Summary

Fixed the nginx Docker build issue by removing the nginx -t configuration test from the Dockerfile. This is the standard approach for containerized nginx deployments where:

1. Build time: The upstream hostname (gateway:4444) doesn't exist yet - it's only created when docker-compose brings up the network
2. Runtime: When the container starts, nginx will still validate the configuration and fail immediately if there are syntax errors
3. Best practice: Configuration validation at runtime is acceptable for Docker deployments since the container won't start successfully if the config is invalid

Changes

• nginx/Dockerfile:21-23: Removed RUN nginx -t and added an explanatory comment
• Nginx will still perform the same validation when the container starts, when it can resolve the gateway:4444 hostname correctly

This is a common pattern in production nginx container deployments where upstream services are defined in docker-compose or Kubernetes networks.
