Subject: Dev dashboard performance improvement

Rather than one query per cell in the arches and repos statistics
tables, we can group these together up front using Django annotations.
This means we only need one query per table.

In my local instance with all of the staging repos imported, this
reduces the total query count on this page from 56 to 26, a rather
marked improvement.
