bmc_hub/scripts/workflow_uninstall.sql

-- Reviewable local-only downgrade, deliberately outside migrations/.
-- Run only via workflow_backup.py after shutdown, verified backup and audit export.
-- Preserves customers, cases, time entries, tags, entity assignments and all actual
-- card transactions/order drafts. Removes new workflow definitions/audit metadata.
