A song's edits are kept through any rebuild, but nothing said which songs
had them. GET /api/jobs and GET /api/rebuild-all now report each song's
edited and set-aside lines, read from its edits file, on the job standing
for the song only, since the runs it replaced would claim the same edits.
Queue cards show them as a badge, and the rebuild dialog lists them per
song and says hand edits are kept.
