Return communication database rows from communication API

This is a pretty big refactor of how communication works to start moving
us in the direction we want to go long-term. This adds the new
communication row and migrates existing reports to add rows for
communication.

There's also a bunch of automatic fixes from the new linter. I should
have added them separately, but whatever.
