Migrate reports to job-server

[bloodearnest]

The following reports are still consuming github outputs:

sqlite> select repo, branch, report_html_file_path, last_updated, is_draft from reports_report where job_server_url == '' order by last_updated DESC;

We should move these over to consuming job-server outputs, then we can delete all the github code from reports.
