fix(ui): stop the album grid eating the year it was sorted by

The year sat inside the same ellipsis box as the title, so it was the
first thing truncation took: a card wide enough for a long album name
never showed its year, and browsing the grid *by year* showed years
only for the albums with short names. The sort said one thing and the
cards showed another.

Title and year are now a flex row where only the title gives way. A
row rather than a second line, because the card's height is what the
virtualizer measures rows by.
