Summary: React ref callbacks may return only `void` or a cleanup function. Align shared callback-ref contracts with that behavior so consumers cannot hide incompatible returns behind `unknown`.

Summary: React ref callbacks may return only `void` or a cleanup function. Align `TRefCallbackFor` and the related shared callback-ref helpers directly with the core Flow React ref types, then update consumers whose callbacks returned incompatible values. This keeps the contracts canonical and avoids introducing a parallel restricted variant. Changelog: [Internal] - Align ref helper types with the React callback contract.
