Don't run queries run in app.ready() - GeneCountType

You sometimes (because of cache, we only check once a day) get this message on startup:

$ python3 manage.py shell
/home/dlawrence/localwork/variantgrid/.venv/lib/python3.12/site-packages/django/db/backends/utils.py:98: RuntimeWarning: Accessing the database during app initialization is discouraged. To fix this warning, avoid executing queries in AppConfig.ready() or when your app modules are imported.
  warnings.warn(self.APPS_NOT_READY_WARNING_MSG, category=RuntimeWarning)

I benchmarked it and it's only 197ns if you have no sample (Shariant) and 9ms per withdrawal or classification if you do (other systems) so will just leave it hooked up all the time

Shariant testing - can publish/withdrawal classification with no noticiable change

Other Testing: This is only used by RUNX1
