Fix `prepare_body` stream detection for `__getattr__`-based file wrappers Resolves #7432 . Add `hasattr(data, "__iter__")` as a fallback stream detector: ```python if ( isinstance(data, Iterable) or hasattr(data, "__iter__") ) and not isinstance(data, (str, bytes, list, tuple, Mapping)): ``` This catches file-like objects that proxy their interface through `__getattr__`, restoring the 2.33.1 behavior without reverting the isinstance(Iterable) modernization for standard iterables.
