[Feature Request] Add Web GUI to control Panda Touch

Since the Panda Touch is already hosting a webpage, it would be AMAZING functionality to add the Panda Touch GUI to this webpage. This would mean that through port forwarding /vpns, the panda touch could be another amazing way to control the printers through the WAN without using BambuLabs software. I love their printers but am hesitant to put full trust in them to allow users to continue to exercise control over their own printers. This way offers an elegant solution to this!

The issue does not name any files, tests, or entry points. Start by locating the webpage currently hosted by Panda Touch and documenting how its printer-control functions could be exposed through the GUI. Done means the scope, security model, and supported controls are agreed and the GUI provides the specified control flow.
