This PR fixes a bug where `lia` was incorrectly solving goals involving ordered types like `Rat` that it shouldn't handle. The `lia` tactic is intended for linear integer arithmetic only. The fix adds `order := false` and `funCC := false` to `NoopConfig`, which is the base configuration for `CutsatConfig` (used by `lia`).
