ADFA-2448: Keep the signature beside the name when it fits

The Column introduced for the round-3 review put every signature on its own
line, so `onDestroy` showed `()` underneath it with most of the row empty.
FlowRow keeps name and detail on one line while there is room and wraps the
detail only when there is not, which still prevents a long name from
squeezing the signature to zero width.
