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.
