hoabba3i-dev/BUB-Panel ? reverse-engineered prompt

Build me a Linux server management panel for VPN and remote access services, with a web dashboard and a terminal based manager. I want one main server that can manage local services and also connect to remote nodes, so I can control users, ports, traffic limits, expirations, and service status from one place.

Support common services like OpenVPN, WireGuard, AmneziaWG, IKEv2, L2TP, SSTP, SoftEther, and a Telegram proxy. Include user actions like create, disable, re enable, delete, bulk management, and generating client configs. I also want a Telegram sales bot that I can configure from the panel, with categories, products, and payment details for selling service plans.

Make it installable on Linux with a simple installer script, use system services where needed, and keep updates safe with backup and rollback behavior. Add login security, audit logs, rate limiting, health checks, and a clean admin interface. If you need current docs or package details, look them up online first.
