Describe the bug
When attempting to apply migrations using ./manage.py migrate I get the following stacktrace:
Traceback (most recent call last):

django.contrib.contenttypes.models.ContentType.DoesNotExist: ContentType matching query does not exist.
I believe the issue is some kind of a "chicken and egg issue", where somehow JobListView defines a filterset on a ContentType that does not yet exist... and this class is attempted to be loaded before the migrations.
Quick and dirty workaround is to comment this line out before running migrations and then removing the comment again, this should allow the plugin to install.
This line is commented out to workaround:
File "/opt/netbox/venv/lib/python3.11/site-packages/netbox_config_diff/views/configuration.py", line 304, in JobListView
object_type=ContentType.objects.get(app_label="netbox_config_diff", model="configurationrequest")
To Reproduce
Install plugin on a fresh database and attempt to run db migrations.
Expected behavior
Migrations run successfully.
