Sort the duel to play by remaining time in Homepage

Is your feature request related to a problem? Please describe.

Currently, the duels to play are sorted by id on the Homepage.

Describe the solution you'd like

It would make more sense to sort them by remaining time, to have the more urgent ones at the top

This change should be pretty straightforward and only require a array sort before the rendering on HomePage.jsx.

If the sort takes too much performance for this page (unlikely), we could add it in the query treatment (in utils/) rather than the rendering component (in pages/).
