fix(light): drop redundant name override on api_input light

The name property returned the source name, which is also the device
name — combined with _attr_has_entity_name=True this produced
entity ids like light.api_input_api_input. Removing it lets the
translation key drive the entity name (Light / Подсветка), yielding
light.<source>_light.
