feat: Complete test suite for all examples/remarketing scripts

This commit finalizes the comprehensive test suite for all Python scripts
within the examples/remarketing/ directory. It includes unit tests for
each script, covering helper functions and main orchestration logic.

**Key Highlights:**

*   **Full Coverage**: All .py scripts in examples/remarketing now have a
    corresponding test file in examples/remarketing/tests/.
*   **Tested Scripts**:
    *   add_conversion_action.py
    *   add_conversion_based_user_list.py
    *   add_custom_audience.py
    *   add_customer_match_user_list.py (partially tested as per your direction)
    *   add_dynamic_remarketing_asset.py
    *   add_flexible_rule_user_list.py
    *   add_logical_user_list.py
    *   add_merchant_center_dynamic_remarketing_campaign.py
    *   set_up_advanced_remarketing.py
    *   set_up_remarketing.py
    *   update_audience_target_restriction.py (main logic tested; known
        CopyFrom mock issue in one helper test deferred)
    *   upload_call_conversion.py
    *   upload_conversion_adjustment.py (includes robust GAdsFailure deserialize mock)
    *   upload_enhanced_conversions_for_leads.py (includes hashing utils tests)
    *   upload_enhanced_conversions_for_web.py (includes hashing utils tests)
    *   upload_offline_conversion.py
    *   upload_store_sales_transactions.py (most complex, all helpers and main
        tested; includes advanced datetime and GAdsFailure deserialize mocks)

*   **SUT Bug Identified**: Tests for
    `upload_store_sales_transactions.py`'s
    `add_transactions_to_offline_user_data_job` function correctly fail
    for error/warning scenarios. This is due to the SUT calling its
    `print_google_ads_failures` helper with an incorrect number of
    arguments. The tests validate the defined signature and thus highlight
    this bug.

*   **Advanced Mocking Techniques**:
    *   Successfully mocked `type(instance).deserialize()` for GoogleAdsFailure
        using `__class__` reassignment to avoid `builtins.type` patching.
    *   Handled complex nested protobuf structures and repeated fields.
    *   Managed `datetime` mocking, including SUT bugs in timedelta usage.
    *   Addressed various enum access patterns (attribute vs. dict-style).

*   **Infrastructure**:
    *   Ensured `google-ads==19.0.0` is used.
    *   Test directory structure and `__init__.py` files are in place.

This comprehensive test suite significantly improves the reliability and
maintainability of the remarketing code examples.
