[DO NOT MERGE] Editor GUI: Experiments with Yew

[kevin-legion]

Experimenting with https://yew.rs/

So far the experience is rather smooth, though some questions start arising when dealing with mutable states for instance.

I could implement a basic resource tree and some auth to make it work.

There is also a Sycamore feature (not on par with the yew version) to compare the two frameworks (must be changed in the Cargo.toml file manually if the app is ran using Trunk).
