Fix SETTINGS placement regression - revert to original logic
Reverted SETTINGS placement logic to the original behavior: - SETTINGS at SelectQuery level only when there's NO FORMAT - SETTINGS at SelectWithUnionQuery level only when there IS FORMAT The previous changes incorrectly added SettingsAfterFormat tracking which caused tests to fail. The original simpler logic is correct. Also restored all metadata.json files to their original state.
