panel: stop the send log breaking short words across lines

The last cell in a row is the one the automatic table layout squeezes first,
and in the send log it holds a fixed two-word link: "Details" was being split
after "Detail" on every row. Holding that cell on one line costs the row
nothing and hands the width back to the status column, which was breaking
"deferred" into "deferre" and "d" for the same reason — the status gets the
same nowrap the timestamp already had, through a class of its own since the
cell had nothing to select on.

Both predate the restyle; they surfaced while screenshotting the send log
against a seeded journal.
