Refactor: Harden for Production

This commit refactors the Node.js server to be production-ready.

- **Strict Production Environment:** The server now checks for . If it is set, the server will refuse to start unless a secure  is provided as an environment variable. This prevents running with the insecure default password in production.
- **Logging:** Added basic logging for successful status updates and failed login attempts.
- **NPM Scripts:** Added a  script to  for starting the server in production mode ().
