Subject: [PATCH] Add dotenv support and update server config

Introduced dotenv for environment variable management and created a .env file for port configuration. Updated server to use HOST and PORT from environment, allowing access from all IPs. Modified Socket.io client connection to use window.location.origin for remote server compatibility.
