NETWORKTWEAKER/AUTO-SCRIPT ? reverse-engineered prompt

Build me a one command VPS setup script for a fresh Debian or Ubuntu server that turns it into an all in one network tunneling panel. I want it to install and configure SSH, Dropbear, stunnel, SSH over websocket, custom UDP, and Xray services for VLESS, VMess, Trojan, and Shadowsocks, with both websocket and gRPC support. It should open the right ports, set up a simple menu to check service status, restart services, run speed tests, change DNS, and clean up expired users automatically. Please include an easy install flow for a brand new VPS, and make it work on Debian 9 and 10, Ubuntu 18 and 20. If it helps, look up current docs online for any service setup details that have changed. Also include the optional extras if they fit naturally, like OpenVPN, Slowdns, Webmin with ad blocking, and a Telegram bot panel. Make the scripts safe to rerun as much as possible and keep the interface simple enough that I can just follow the prompts.
