Test file for Metanet Desktop Authentication using py-sdk

This test demonstrates how to authenticate with go-wallet-toolbox using py-sdk
and execute createAction requests.

Usage:
    python test_metanet_desktop_auth.py

Requirements:
    - py-sdk installed
    - Valid private key for testing

Note: This test works independently without requiring a running go-wallet-toolbox server.
