refactor(ci): reduce refresh-data to a dump smoke-test

Drop the weekly cron from refresh-data.yml (it duplicated weekly-refresh.yml, which now owns the Monday enrich+gate+dump+PR run). Keep the push:app/** + manual triggers so a change to engine code still verifies that app.dump generates end-to-end.
