[BUG] Django's override_settings does not work for Ninja settings

[OscarVanL]

Describe the bug
It seems I cannot use Django's override_settings for the NINJA_NUM_PROXIES setting.

Specifically, the patched setting does not work in this case.

@override_settings(NINJA_NUM_PROXIES=3)
@override_settings(NUM_PROXIES=3)
def test_throttle_proxied(self):

But this does work:

@patch("ninja.conf.settings.NUM_PROXIES", 3)
def test_throttle_proxied(self):

From what I can understand, for some reason Ninja has its own config that is separate but related(?) to the underlying Django config. It seems to break this standard Django settings patching annotation.

Expected behaviour

Patching the settings of third-party Django dependencies usually works fine for me, e.g. I use @override_settings(AXES_ENABLED=False) in many of my tests.

I had a look at how axes handles its application settings. It looks different:

from django.conf import settings
settings.AXES_ENABLED = getattr(settings, "AXES_ENABLED", True)

For this, it seems to just use the default global settings and sets the default only if the user has not set the setting in their own settings.py file.
