worklog: widen ?q= search to paths + refs, not just prompt

An ingested render row has an empty prompt, so filtering Queue & History by
filename found nothing. Widen the /v1/worklog ?q= filter to also match kind,
output_prefix, output (the landed path), and refs — so a render is findable by
its filename or source image, not only by a typed prompt. Test covers filename,
ref, and prompt matches.
