Use the classic navigation components for ImageElements

Follow-up from this thread on !596 (merged):

The vue/Image/Elements.vue components was initially used in the sidebar, and therefore had limited space to list elements. It has now been moved to a separate page and could therefore use the same navigation components, with the two list and thumbnail layouts, etc. as everywhere else.

This could require changes on those navigation components as they were only meant to use ListElements and ListElementChildren, but adding ListImageElements should not be too difficult since they have the same serializers and similar filters.
