DRF's RelatedField asserts queryset is not None (unless read_only) at
__init__ time, i.e. when the class body of the Serializer is
evaluated - not when the field is later used. The previous code passed
queryset=None and tried to patch it in the serializer's own __init__,
which never ran in time because construction of the field itself
already raised. Pass the real querysets directly at class-body level
instead, matching the standard DRF/NetBox pattern; the deferred
per-instance model imports are no longer needed since serializers are
only imported once all apps are ready anyway.
