Refactoring step are in separeted commits to facilitate the code review.

• reorganize plugins header block: inline displaySelectAll, put filters radio button on a new line, inline displayFilters method
• move warning message line under filters div otherwise it shifts the filters div when it appears and disapears and makes a bad visual effect and adjust positionning with margin-top
• fix font size: use default font size variable and fix the value
• use rem unit because it's relative to document root value
• format code

LGTM as we did this in mob, since commits are split, it needs a rebase before merging !

What would be the behavior of the bot if you approuve before the rebase ?

@P4uline it would merge the PR 😅
I'm not sure there is something else than "Draft status" to guarantee that the PR won't be merged by the bot, once it is approved (maybe the "Can't merge" label, but IIRC it still happened sometimes)
