What?

In this PR:

• Implement the local font asset upload in the React App

Why?

To allow us to implement the user ability to add more configuration options.

How to test:

• Add a few fonts a test if everything is working as before.

Extra info:

⚠️ This PR has as base the branch of #260 to re-use some of the components implemented in that branch.

If I do that all the changes from add/fonts-sidebar will show in the diff. What would you want to do that?

No. It adds more noise.

I would like this to be independent with related changes so it would be easy to review and merge.
If you think it has to depend on the changes from #260, let's mark this as draft PR for time being.

I'm closing this PR in favor of this other one that can be merged independently of other code changes: #268
