The Kommende Fristen / Termine cards forced the page wider than the
viewport on mobile. Root cause: .dashboard-col is a CSS Grid item with
the default min-width: auto, so its track sized to the min-content of
the deeply nested .dashboard-list-link content (nowrap title + ref +
badge), expanding the single-column grid track to ~641px even when the
viewport is 375px.
Set min-width: 0 on .dashboard-col so the grid track can shrink to its
column width and the existing text-overflow: ellipsis on the title/ref
spans does the rest.
Verified at 375x900: no horizontal page scroll, columns 327px each,
long titles truncate with ellipsis. Desktop >=768px unchanged
(1fr 1fr -> 504px each at 1280 wide).
