fix(voice): show FIRMS and ALPR entity labels translated on the voice card

The pointer chip, its live-region line and the get_entity_context card
title now translate the English entity labels the FIRMS and ALPR layers
register ("Fire · FRP {frp} MW", "ALPR camera"). Other names, such as
callsigns and place names, show as they came.
