Give Galaxy timestamp cards double-width boxes

The Last Deploy and Last Refresh metric cards hold full timestamps that
wrapped to three or four lines in a single-width card. Add a Wide option
to MetricCard (grid-column: span 2) and set it on both Galaxy timestamp
cards. Also switch .metric-value to overflow-wrap: break-word so a date
token is never split mid-value.
