Drop the ellipsis in week and day event chips too (#164)

#183 only covered the month grid, but a week column is just as narrow. The
all-day chips and the drag copy take the same treatment; the timed blocks
only when they are showing a single line, since wrapping needs softWrap on
and clipping with it on breaks at the last whole word.

The rule now lives in one helper instead of being copied per chip.
