Python: Warn on unsupported AzureAIClient runtime tool/structured_output overrides

[eavanvalkenburg]

Summary

• track AzureAIClient agent-creation tool names and structured output configuration
• log a warning when runtime tools or structured_output differ from creation-time configuration and direct users to ResponsesClient
• update AzureAIClient run option pruning to only remove keys that map to the concrete options TypedDict
• add tests in the existing azure-ai client test file for runtime warnings and typed-dict-based option pruning behavior

Validation

• uv run ruff format packages/azure-ai/agent_framework_azure_ai/_client.py packages/azure-ai/tests/test_azure_ai_client.py
• uv run ruff check packages/azure-ai/agent_framework_azure_ai/_client.py packages/azure-ai/tests/test_azure_ai_client.py
• uv run --directory packages/azure-ai pytest tests/test_azure_ai_client.py -k runtime_tools_override_logs_warning or runtime_structured_output_override_logs_warning or prepare_options_excludes_response_format or prepare_options_keeps_values_for_unsupported_option_keys -q

Pull request overview

This PR improves AzureAIClient ergonomics by tracking agent-creation configuration (tools + structured output) and warning when callers attempt unsupported runtime overrides, while also changing how request options are pruned to be based on the concrete client options TypedDict.

Changes:

• Track creation-time tool names and structured output configuration; warn on runtime mismatches and point users to ResponsesClient.
• Replace fixed “exclude list” pruning with TypedDict-driven pruning logic.
• Add unit tests for runtime-override warnings and TypedDict-based option pruning.

python/packages/azure-ai/agent_framework_azure_ai/_client.py	Adds runtime override warnings + refactors run option pruning to depend on concrete options TypedDict.
python/packages/azure-ai/tests/test_azure_ai_client.py	Adds tests for the new warnings and for TypedDict-based pruning behavior; updates test client factory.
