`prefetch_related()` does not filter on the tenant field

The WHERE clause generated is just like`WHERE id IN (...)`

`prefetch_related` with the `Prefetch` object works:
```
prefetch_related(
Prefetch('field', Model.objects.all())
)
```

This workaround sometimes helps, but, for example, it does not work with @[django-auto-prefetch](https://github.com/tolomea/django-auto-prefetch)

P.S. `select_related` works as expected, it does filter by tenant.

Start by reproducing the tenant-filtering behavior with the reported prefetch_related() call and compare its generated WHERE clause with Prefetch and select_related(), which the issue identifies as working. Check how django-auto-prefetch exercises this path, then consider the work done when prefetch queries consistently include the tenant constraint without breaking the reported working cases.
