Address review: self-contained samples, fixture registration, scoped feature routing

- Declare the sample table in both companions so each compiles on its own.
- Register no-changecompany-in-upgrade and changecompany-runs-triggers-in-the-calling-company in review-fixtures.json.
- Limit the Feature Data Update rule to UpdateData/AfterUpdate and their reachable helpers; read-only IsDataUpdateRequired/ReviewData preflight is permitted and shown as a clean control.
- Add feature data update execution to al-upgrade-review applicability and not-applicable scope.
