Migrate reports to job-server

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.

Start with the SQL query in the issue and inspect the reports code paths that consume GitHub outputs for each listed record. Trace how those reports should consume job-server outputs instead; the work is done when all listed reports use job-server outputs and the obsolete GitHub code can be removed.
