refactor: App to functional component

[JF-Cozy]

This PR is a part [2] of multiple PR about the new sort logic in the application. Tests will maybe failed and probably don't after merging previous PR and rebasing this one.

• Refactor App to use functional component / hooks
• (*) Extract the main query to new file
• Cleanup browser index (app init) and store configuration

(*) the Query is still not using hooks. It is the very first refactor, the hook will comes in an other PR

[Crash--]

Tests are red.

Also, if I had to be a pain in the ass I'd say you should have made a commit for the hook translate, one for the breakpoint etc.

Yes I know, as I said in the PR description Tests will maybe failed and probably don't after merging previous PR and rebasing this one.. So now previous PR is merged, this one rebased and it's ok.

Hmmm hooks like those just add a const and remove entries in the export. And a wrapper in the breakpoint case... so just few changes, but ok next time I will do it by hooks.

It's just way easier to review commit by commit with one commit dedicated to one thing.

Can be merged if ok, previous PR #661 was merged
