Fix temperature graph on hardware overview dash

Fixes the hardware overview dashboard to use the correct metric for
displaying drive temps. Now uses an `or` to display whichever metric is
compatible with the drives in the system. The two metrics are
temperature_case_raw_value and temperature_celsius_raw_value.
