Add a "not owned" quick filter and horizontal tile view to Card Search

"Not owned" moves into the shared Quick filters icon-toggle row (hidden on
the Library tab, where it'd always be a no-op since that view is owned-only
already) instead of a standalone button.

Tiles view gains a "Horizontal" toggle that rotates actually-horizontal
cards (Battles, Planes, Phenomena) into their natural landscape orientation
via a container-query-sized wrapper, spanning two grid columns so the
rotated card isn't squeezed into a single portrait column's width and left
too small to read.
