fix: add translations for the eight new MOD sensors

tests_ha enforces that every SENSOR_DEFINITIONS entry has an entity.sensor name
in strings.json and translations/en.json; without one the sensor is unnamed in
the UI. The eight added for #372/#373 had none.

Caught by CI rather than locally: tests_ha needs Home Assistant and only runs on
Linux, so 'pytest tests/' passing says nothing about it. Verified this time by
replicating the assertions against an AST parse of sensor.py.
