Improve eslint config

[kuuak]

Improve eslint config to set code standard by default.

As shared internally the fact that all imports must be grouped & sorted the same way throughout the project is a game changer to keep files organised and for git diffs to be more performant.

Find below the multiple commits done in FWT for the eslint to be fully working:
