List display for proposals' index

The idea here is to show more proposals on one page. We could re-use the list display from the budget component. A must would be able to play with density (like in gmail). We made a first iteration for this : https://concertations.nouvelle-aquitaine.fr/processes/Feuillederoute-economienumerique/f/39/proposals?display_type=list It would have to be rethinked taking into account the new card design.
