-- Remove company_id columns and FK constraints from all domain tables.
-- The company table stays as store settings, but tenant scoping is removed.
-- In a SaaS deployment, isolation is at the database level, not application level.

-- Drop company_id from each table (CASCADE drops the FK constraint automatically)
