feat(extui): don't enter pager for routed message #34679

Problem:  Messages routed to the pager to be shown in full, enter the
          pager automatically, yielding another "press-q-prompt".

Solution: Only enter the pager when requested explicitly. Otherwise,
          close the pager on the next typed mapping, unless that mapping
          entered the pager.
