Create a dummy Letzshop order for testing purposes.

This script creates a realistic Letzshop order in the database without
calling the actual Letzshop API. Useful for testing the order UI and workflow.

Usage:
    python scripts/create_dummy_letzshop_order.py --store-id 1
    python scripts/create_dummy_letzshop_order.py --store-id 1 --status confirmed
    python scripts/create_dummy_letzshop_order.py --store-id 1 --with-tracking
