fixed editors style to avoid overflow

[LeonardoMussato]

Description

I noticed that on the JSON editor when it opens it shifts the layout and the entire page becomes scrollable. Now with these fixes, I changed all the heights of the editors to avoid defined values similar to calc(100vh - 22px) and use only height: 100% and display flex. The change is visible on the bottom of the page.
