feat: add ha_info, ha_shopping_items endpoints and avahi mDNS service file for HACS integration
- api/index.php: new haGetInfo() endpoint (unique_id, version, instance, items count)
- api/index.php: new haGetShoppingItems() endpoint (Bring! + internal shopping list)
- api/index.php: haInventorySensor() now accepts ?expiry_days=N query param
- api/cron_smart_shopping.php: auto-register avahi mDNS service if avahi-daemon present
- docker/avahi-evershelf.xml: Zeroconf _evershelf._tcp service declaration
- .env.example: add INSTANCE_NAME variable (used by HA integration for device label)
