Fix MAP type test expectations in cursor and pandas tests

- Update test_complex to expect MAP values as converted dictionaries instead of strings
- Update pandas test_as_pandas with same MAP expectations
- Fix DBAPI type assertions for MAP columns
- All CI failing tests now pass locally

MAP type converter now properly converts {1=2, 3=4} → {'1': 2, '3': 4}
