The for_save flag wasn't properly propagated when resolving expressions, which
prevented get_db_prep_save() from being called in some cases. This affected
fields like JSONField where None would be saved as JSON null instead of SQL NULL.

Regression in 00c690efbc.

Thanks to David Sanders and Simon Charette for reviews.

* Fixed a log injection possibility by migrating remaining response logging
to ``django.utils.log.log_response()``, which safely escapes arguments such
as the request path to prevent unsafe log output (:cve:`2025-48432`).
* Fixed a regression in Django 5.2 that caused :meth:`.QuerySet.bulk_update` to
incorrectly convert ``None`` to JSON ``null`` instead of SQL ``NULL`` for
``JSONField`` (:ticket:`36419`).
