feat: refactor API gateway and CLI utilities for improved functionality

- Updated the API gateway documentation to reflect changes in architecture and functionality, emphasizing its role as a multi-functional entry point for decentralized services.
- Refactored CLI commands to utilize utility functions for better code organization and maintainability.
- Introduced new utility functions for handling peer normalization, service management, and port validation, enhancing the overall CLI experience.
- Added a new production installation script to streamline the setup process for users, including detailed dry-run summaries for better visibility.
- Enhanced validation mechanisms for configuration files and swarm keys, ensuring robust error handling and user feedback during setup.

 ### Node Unified Gateways
 
 Each node is accessible via a single unified gateway port:
 
 ```bash
 # Node-1 (port 6001)
-curl http://node-1.local:6001/health
+curl http://localhost:6001/health
