fix(tenant): resolve desktop retry article id via publish record/batch

Fall back to looking up article_id from publish_records or publish_batches
when the desktop task payload lacks article_id at the top level. Covers
payloads that only carry content_ref.{article_id,id}, publish_record_id,
or publish_batch_id, preventing spurious 40096 errors when retrying
older desktop tasks.
