bodaue/telegram-bot-vpn — reverse-engineered prompt

Build me a Python Telegram bot for selling VPN access. A user should be able to open the bot, see a simple welcome message, choose a VPN access option, pay with YooMoney, and then get the VPN access details after the payment is confirmed.

Keep it simple and practical. I need config through an env file for the Telegram token, YooMoney settings, prices, and the VPN access text or file that gets sent after purchase. Add basic admin controls so I can see recent orders and manually resend access if something goes wrong.

Make it ready to run on a small Linux server, with clear setup steps and a systemd service example. Please include simple error handling, payment status checking, and friendly Telegram messages in Russian or easy to edit text constants. Use common Telegram bot libraries for Python, and look up current YooMoney and Telegram docs online if you need to.
