      SERVER-134925 declared MongoDB's untimestamped writes to disaggregated (layered)
      tables with allowOneUntimestampedWrite() so WT's commit-timestamp check
      (WT-18585 / WT-18608) can be enabled. That suppresses the error, not the
      problem: an untimestamped commit is never picked up by the ingest->stable drain,
      so the content stays in the local ingest table and is lost when ingest is
      discarded.

      For each site marked TODO SERVER-134926, determine whether a real commit
      timestamp can be supplied and remove the declaration where it can. Some sites run
      before any timestamp exists and may need a different answer - a synthetic
      bootstrap timestamp, a WT-side exemption, or doing the work before the connection
      is disaggregated.
