fix: update test patches to use new agent_framework.openai classes

Updated mock patches in test_agent_framework_helper.py to reference:
- agent_framework.openai.OpenAIChatCompletionClient (was azure.AzureOpenAIChatClient)
- agent_framework.openai.OpenAIChatClient (was azure.AzureOpenAIResponsesClient)
