Two issues fixed:
1. Cloud pollers (organization_id = nil) were causing access denied errors
when superadmins tried to view them. Now allows access if user is
superadmin and agent is a cloud poller.
2. Ecto.NoResultsError was being raised without required :queryable option,
causing KeyError crash. Now properly raises with queryable parameter.
Error was:
KeyError: key :queryable not found in []
(ecto 3.13.5) lib/ecto/exceptions.ex:203: Ecto.NoResultsError.exception/1
(towerops) lib/towerops_web/live/agent_live/show.ex:16: mount/3
