fix(cloud): pin peer file-card filename + action buttons to the bottom (#11)

Make each peer file card a flex column filling its grid cell (flex flex-col
h-full) and pin the body row (filename + Play/Download) with mt-auto, so cards
with a media preview and cards without line their footers up across the row.
