chore: Upgrade Python requirements (#944)

* chore: Upgrade Python requirements

* fix: pin pytest-django<4.13.0 to fix Django 4.2 compatibility

pytest-django 4.13.0 (released 2026-08-06) references
`_pre_setup_ran_eagerly` which is a Django 5.x attribute not present in
Django 4.2. Pin to <4.13.0 so the django42 tox env continues to work.
