-- Deprecated helper script.
-- Use versioned goose migrations instead:
--   1) make migrate-up-to v=20260414
--   2) import legacy dump rows into table `helicopter_old_import`
--   3) make migrate-up-to v=20260415
--
-- Notes:
-- - Data is migrated into `helicopters` (backend table name) with UUID bytes (BINARY(16)).
-- - `counter`, `service`, `disabled`, `visible` from legacy dump are ignored.
-- - `is_active` is forced to 1.
