Rework UI/UX using designer inputs

[mwestphal]

Context
F3D switced UI framework for ImGui in F3D 3.0
However, the new UI is merely a recreation of the old UI.

So lets:

• Add HDRI information on the top left similar to the file information
• Use the color palette shared below
• Improve dropzone as shared below

Hello !

I'm interested in this issue, nevertheless it could be good to list features that we want to redesign directly here. Idk may be drop zone, cheatsheet, command console, etc... with the actual state of the GUI. I think It can help people to get involved in the discussion.

I asked right on figma file to see proposals and I will try to make a mockup this week.
