- Add scanTelemetryValues() function to unpack all telemetry fields (Power, Environment, AirQuality)
- Update GetMapNodes query to select all telemetry columns, not just voltage and battery
- Use scanTelemetryValues() in getTelemetry() and scanMapNodeWithTelemetry() to avoid duplication
- Ensures consistent telemetry unpacking across different scanner functions
