+This migration does two things:
+1. Change new `usage.billing_status` default from `settled` to `pending`.
+2. Repair only the clearly-safe inconsistent historical rows for production:
+   - failed/cancelled zero-cost rows that were marked settled are converted to void
+   - terminal rows missing finalized_at are backfilled from created_at
+
+Ambiguous positive-cost settled rows are intentionally left untouched for manual audit.
+
+All data updates are batched (10000 rows per iteration) to avoid long-held locks
+and excessive WAL generation on large usage tables.
