/**
* Terminal WebDoor - SSH and Telnet Gateway
*
* This webdoor provides web-based terminal access to remote SSH and Telnet hosts.
* It connects to an external proxy server (e.g., terminalgateway) that handles
* the actual SSH/Telnet connections.
*
* Protocol Support:
* - SSH: Requires proxy server with SSH client support
* - Telnet: Requires proxy server with Telnet client support
*
* The frontend sends connection requests with protocol type ('ssh' or 'telnet')
* to the proxy server via Socket.IO events:
* - 'connect-ssh' for SSH connections
* - 'connect-telnet' for Telnet connections
*
* Configuration:
* - Hosts are defined in config/webdoors.json under the 'terminal' key
* - Each host must specify: hostname, port, and proto ('ssh' or 'telnet')
* - The proxy server address is configured via TERMINAL_PROXY_HOST and TERMINAL_PROXY_PORT
