Fix false positive bad-instantiation for dataclass implementing protocol with __dataclass_fields__

[fangyi-zhou]

Summary

• Fixes a false positive bad-instantiation error when a @dataclass implements a Protocol that declares __dataclass_fields__: ClassVar[dict[str, Field[Any]]]
• This regression was introduced by [conformance] Handle protocol subtyping checks with instances & objects #2428, which synthesized __dataclass_fields__ as a ClassVar for dataclasses
• Root cause: calculate_abstract_members used get_non_synthesized_class_member_and_defining_class to look up fields, which skips synthesized fields. The dataclass's synthesized __dataclass_fields__ was invisible, so the MRO traversal found the protocol's uninitialized ClassVar instead — flagging it as abstract
• Fix: before the existing check, use get_class_member (which includes synthesized fields) to detect concrete implementations. If the class already has a non-abstract, non-uninitialized implementation, the requirement is satisfied and we skip it

Fixes #2477

Test plan

• Added regression test test_dataclass_protocol_dataclass_fields in pyrefly/lib/test/dataclasses.rs
• test.py

I used Claude code to fix the regression and the fix looks reasonable.
