"""HA Full Inventory — run inside the HA container via docker cp + docker exec.

Usage:
    docker cp /tmp/ha_full_inventory.py homeassistant:/tmp/
    docker exec homeassistant python3 /tmp/ha_full_inventory.py

Lists all devices (with area, manufacturer, model, MAC), all integrations, and
all entities grouped by domain. No API token needed — reads .storage/ JSON directly.
