The card's overflow clip cut off the viewed mark and the file menu when a
narrow header also held a long path, the changed tag, and a rename badge;
before the cards, the list could still scroll sideways to them.
The icon, path, changed tag, and badge now share one box that shrinks to
any width, so the counts, the viewed mark, and the menu after it stay
whole. The path and badge shorten in proportion to their widths, the
changed tag is capped at 30% of the box with an ellipsis, and the path
keeps its full-path tooltip.
A 390px e2e renames a long file, changes it after it is marked viewed,
and checks that the mark and menu stay inside the card, the mark still
toggles, and hovering the name shows both paths.
