Add background workers to regularly poll SNMP sensors and interfaces: - Create PollerWorker GenServer to poll SNMP devices - Poll all sensors for temperature, voltage, CPU, memory, etc. - Poll all interfaces for bandwidth, errors, and discards - Save time-series data to snmp_sensor_readings and snmp_interface_stats - Integrate with monitoring supervisor to auto-start pollers - Use same interval as connectivity checks (minimum 30 seconds) - Add list_snmp_enabled_equipment function to Equipment context Pollers start automatically on app boot for all SNMP-enabled equipment and run independently of connectivity monitoring.
