fix(uipath): restore line_by_line support in ExactMatchEvaluator

ExactMatchEvaluator was a pure re-export from uipath_eval which lacks
line_by_line_evaluator support in its OutputEvaluatorConfig. Restore
by defining a local ExactMatchEvaluator that extends uipath's
OutputEvaluator (which has line_by_line logic in validate_and_evaluate_criteria).
Also fix import sort in output_evaluator.py.
