Umbra Tools b259060808 Record two more consequences of the mislabelled Spanish production
Measured on oldbox:

* The UmbraTrans dashboard reports the Spanish lane as "complete".
  project_status.py derives each language's state from the presence and
  chapter count of deal-hunter-<tag>/runs/ch-N/translation.json, and
  deal-hunter-es has 32 of 32. It never looks at what the text says, so a
  directory name and a file count are standing in for a measurement. The
  other nine target languages correctly report not_started.

* A real Spanish run would silently reuse the Chinese translations.
  pipeline.py caches by file existence and the run directory is chosen by
  the caller, so a Spanish run pointed at deal-hunter-es without --force
  would skip drafting and publish the Chinese under a Spanish name.

Neither was fixed here: the UmbraTrans checkout on oldbox is behind and
dirty, and the script check belongs in the same place as the ingest's.
