Separate Docker build into dedicated script

- Create build-image.sh for dedicated Docker image building
- Remove Docker build logic from build.sh to focus on Node.js app only
- Add comprehensive instructions for running and pushing Docker images
- Improve build script modularity and separation of concerns
