Replace individual Repo.insert() with Repo.insert_all() for sensor readings, interface stats, processor readings, and storage readings in agent channel and device poller worker. Add partial/composite database indexes for common query patterns. Dashboard now uses GROUP BY aggregation instead of loading all devices. DeviceLive.Show only reloads data for the active tab on PubSub events. DeviceLive.Index debounces status changes and skips quota queries on updates. Agent polling preloads filtered to monitored sensors/interfaces only.
