match index-less device strings to hardware units in the detection models picker

A config with `edgetpu:usb` was reported as hardware that wasn't found, because the picker compared device strings exactly and the probe reports the unit as `edgetpu:usb:0`. A device without an index now resolves to the first unit of that kind, so the hardware dropdown, the unit checkboxes, and the model summary all recognize it.
