search: move facets at bottom on small screen

[zannkukai]

On small screen, the facets (normally displayed on left sidebar) moves
to the bottom of the screen. So, the search result hits are directly visible
on small screen.

I tested and I think this can be improved as this:

<div class="col-md-5 col-lg-3 mb-3 mb-md-0" *ngIf="showSearchInput"> // Line 36

<div *ngIf="resultsText$ | async as resultsText" class="col"> // Line 46

class="col-md-5 col-lg-3 order-2 order-md-1"> // Line 141

<div id="recordlist" class="col order-1 order-md-2"> // Line 208

Moreover, I discussed with @jma and @Garfield-fr and they think a better solution would be to have a toggle (hamburger) to show / hide aggregations.
This is a quick solution, but it will probably change in the future.
