1.4.0 regression: enum.member(value=callable) leaves the wrapper in self.value #5279

Describe the bug

The keyword form member(value=decimal) is valid and works at runtime. In 1.4.0, replacing it with member(decimal) makes the diagnostic disappear. The annotation is a normal callable payload contract; no suppression is needed with 1.3.2.

Reproduced with Pyrefly 1.4.0 and CPython 3.14.8 on macOS. Pyrefly 1.3.2 accepts the same example under --preset all.

Reproducer

from collections.abc import Callable
from enum import Enum, member

def decimal(value: int, /) -> str:
    return str(value)

class Format(Enum):
    DECIMAL = member(value=decimal)

    def render(self, value: int, /) -> str:
        formatter: Callable[[int], str] = self.value
        return formatter(value)

assert Format.DECIMAL.render(42) == "42"

Commands

uvx --from pyrefly==1.3.2 pyrefly check --preset all callable_member.py
uvx --from pyrefly==1.4.0 pyrefly check --preset all callable_member.py
python callable_member.py

The runtime assertion passes. The configuration only sets preset = "all" and python-version = "3.14".

Pyrefly 1.4.0 output

`member[(value: int, /) -> str]` is not assignable to `(int) -> str` [bad-assignment]

Mypy 2.4.0 (strict, without project plugins) and Pyright 1.1.414 accept this example.
