the download dialog stops growing to fit its titles

A long video title pushed the modal wider than itself and ran out of the card. The title had `truncate`
and its parents had `min-w-0 flex-1`, and none of it bit.

DialogContent is a GRID. A grid item defaults to `min-width: auto` — it refuses to shrink below its
content — so the list container expanded past the dialog's own `max-w-lg`, the card grew with it, and
`truncate` never had a width to truncate against. Every constraint below that point was measured against
a box that had already given up.

`82d24a8f` made the card a column, which was a real fix for a real half of this: the title, thumbnail
and button used to share a line and the title won. But a column still cannot be narrower than the
widest thing the grid above it will allow, so the fix held only until a title long enough came along.

Worth knowing beyond this dialog: every DialogContent in the app is that same grid, so any dialog
holding unbreakable content has the same trap waiting. Fixed here rather than in the shared component,
because changing the layout of every dialog in the platform to fix one modal is not a change to make
without asking.
