Sensor weights already existed, but only as a second step after saving
a zone with two or more sensors, with fields labelled by raw keys such
as weight__sensor.living_a, so they were easy to miss.
The zone form now says that choosing two or more sensors leads to a
sensor-weight step. That step uses numbered fields ("Sensor 1 weight",
English and Romanian) and its description lists which sensor is which
by friendly name. Editing a multi-sensor zone shows the saved weights.
Stored data is unchanged.
