Software design fixes: - Add proper aliases for all nested modules - release.ex: Ecto.Adapters.SQL - packet_consumer.ex: Aprsme.Cluster.PacketDistributor - cleanup_scheduler.ex: Aprsme.Workers.PacketCleanupWorker - health_check.ex: Ecto.Adapters.SQL - status_live/index.ex: Aprsme.Cluster.LeaderElection - packet_receiver.ex: Aprsme.Cluster.LeaderElection - packet_distributor.ex: Aprsme.Cluster.LeaderElection, AprsmeWeb.MapLive.PacketStore Security: - Update .sobelow-skips for false positive SQL injection warning (div is builtin function) All 13 software design suggestions now complete. All 13 warnings previously fixed. Remaining: 42 refactoring opportunities (complex/nested functions)
