#3365: the losses prompt shows every detail line and how many have none

The prompt showed 3 detail lines per category under a bare count, which read
as the project's total. The headline now says how many occurrences are left
out or changed, every line the report keeps shows, and "… and N more" counts
the rest. The import report records that number as `unlisted` (an unmapped
effect's line covers all its instances); unmapped effects are listed most
used first.
