Feature: surfacing wizard

[broncosis]

Machine Context

I am building a cnc router and in my travels I had esp32 grbl on my controller with esp3d web ui while its similar theres a few tweeks I like on on the fluidnc side but I would really like to have the the surfacing wizard https://github.com/luc-github/ESP3D-WEBUI/blob/2.1/www/js/grbl.js I think I have found most of the code here but getting this into a working form on a machine is a little beyond me. I'm not great with coding.

Feature Description

its a extra tab in the grbl window that give you the ability to surface a piece of material or the bed with out opening cad some times you just want something to be flat

Other Approaches

I have looked for other options but nothing is quite this simple

How I Can Help

when I get a second board I am happy to dig in and test and noddle with code I might even be able to do some of the changes with a bit of direction
