fix(v2): render match-rom covers at full width in Safari

The manual "Match ROM" dialog wrapped each GameCard in a block-level
cell, so the card's aspect-ratio-derived width resolved against a
shrink-to-fit containing block. WebKit collapses that circular case to a
near-zero width, rendering covers as thin slivers (Chromium is fine).

Lay the cell out as a flex container so the card sizes via flex intrinsic
sizing, the same path the gallery row already uses.

Fixes #3761
