Removes API key (local auth) dependencies for all Azure Cognitive Services targets in scenarios and in favor of Entra ID (Azure AD) token-based authentication.

Pull request overview

This PR removes API key authentication dependencies from Azure Cognitive Services targets in PyRIT scenario files, replacing direct os.environ.get("AZURE_OPENAI_GPT4O_UNSAFE_CHAT_KEY") calls with get_azure_openai_auth(endpoint) to enable Entra ID (Azure AD) token-based authentication. This is a follow-on to PR #1404 which made the same change in initializers and notebooks.

Changes:

• Replaced api_key=os.environ.get("..._KEY") with api_key=get_azure_openai_auth(endpoint) in six AIRT scenario files and one Foundry scenario file, caching the endpoint in a local variable to avoid redundant os.environ.get() calls.
• Renamed the G NetworkX graph variable to g in 1_anecdoctor_generator.py (and its .ipynb pair), aligning with PEP8 lowercase variable naming.
