Fix standalone execution without Home Assistant dependency

Import INVERTER_PROFILES from emulator.models instead of directly
from custom_components package. The models.py already uses importlib
to load the module without triggering Home Assistant imports.

This allows the emulator to run on any PC without requiring Home
Assistant to be installed.
