feat: dashboard weighs quality and splits work by a list field

The insights reading adds quality (open bugs per priority, bugs created
and closed per week for 8 weeks, QA returns and passes per area over 90
days, bugs reported in the 14 days after each of the last three
releases) and, for each list custom field, open tickets per option. The
dashboard shows both; the field to split by can be picked.
