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.| # | Tool | Arguments | Result |
