Add missing device class mappings for distance, power_factor, humidity, pressure (#430, #435)

Aligns sensor.py and number.py METRIC_TYPE_TO_DEVICE_CLASS with the
DEVICE_CLASS_METRIC_TYPES list in merge_topics.py. Without these
mappings, units for affected metrics (e.g. km on EV odometer/range)
were silently dropped.
