-- Destructive cleanup for the SOP single-version migration.

-- The statements discover constraint/index names because deployments may use
-- different GORM naming conventions.
-- The application does not use database foreign keys. Remove every existing
-- foreign key in the database first so no historical constraint remains and
-- no constraint blocks the old SOP column cleanup.
