amirh00sain/SpiderPanel ? reverse-engineered prompt

Build me a web control panel for managing a proxy or subscription service.

I want a clean dashboard where I can create and manage users, set traffic limits and expiration dates, generate subscription links and QR codes, and keep track of nodes and workers with simple health checks. It should also have a scanner page for checking IPs, ports, and SNI details, with results that are easy to copy on mobile.

Please include Telegram workflows too, so I can post new subscriptions to a channel and run a simple sales flow where people pick a plan, upload payment proof, and I can approve or reject the order. Make the app work well on a VPS or in a container, and make the public subscription links work even if the final domain is only known after deployment.

Use a modern responsive UI, keep everything on port 8080, and if you need current deployment or Telegram docs, look them up online.
