fix: clip overflowing conference link in dashboard table (#790)

The Conference cell is a grid item with the default min-width:auto,
so a long unbroken URL forces the grid track wider than its
minmax(140px, 1fr) size and bleeds visually into the Status column.
Clip it with overflow:hidden/ellipsis and expose the full value via
a title attribute.
