Desktop token pair listing component / backdrop

[murillojorge]

We're having trouble setting the height of the backdrop on desktop browsers, sometimes it cuts important information and become an obstacle for the user flow.

In my opinion we should create an alternative to the backdrop for desktop only. Something simple as a container that is a sibling of the inputs so the user can scroll easily, look at the listings and go back up to the input controllers. As previously discussed this could correct the issues we are experiencing.

Mobile is working fine with the current MUI specs.
