## Summary ArrayType and MultisetType were calling `to_sql_type` on elements in `from_sql_type`, which is the wrong direction. This caused decoding of ARRAY<DATE> and MULTISET<DATE> to fail with `AttributeError: 'int' object has no attribute 'toordinal'`. Fixed by calling `from_sql_type` instead (matching MapType.from_sql_type behavior). ## Brief change log - Add: test_array_from_sql_type_converts_elements - Add: test_multiset_from_sql_type_converts_elements - Fix: ArrayType.from_sql_type to decode elements via from_sql_type - Fix: MultisetType.from_sql_type to decode elements via from_sql_type ## Verifying this change - [x] Added tests that verify the fix (test suite will pass on CI) - [x] Related to existing test for MapType.from_sql_type consistency - [x] Regression tests for ARRAY<DATE> and MULTISET<DATE> ##### Was generative AI tooling used to co-author this PR?
