Python: Add file_ids support to AzureAIAgentClient.get_code_interpreter_tool()

[giles17]

Summary

Adds file_ids and data_sources keyword arguments to AzureAIAgentClient.get_code_interpreter_tool(), matching the underlying azure.ai.agents SDK CodeInterpreterTool constructor. This enables users to attach uploaded files for code interpreter analysis.

Problem

AzureAIAgentClient.get_code_interpreter_tool() accepted no parameters and always returned a CodeInterpreterTool() without file references. Users had no way to attach uploaded CSV/data files through the framework's factory method.

Changes

• _chat_client.py: Updated get_code_interpreter_tool() to accept file_ids and data_sources keyword-only parameters, forwarding them to the SDK's CodeInterpreterTool(...). Added VectorStoreDataSource import.
• test_azure_ai_agent_client.py: Added 3 tests covering basic instantiation, file_ids forwarding, and _prepare_tools_for_azure_ai correctly populating tool_resources.

Usage

from agent_framework.azure import AzureAIAgentClient

# With uploaded file IDs
tool = AzureAIAgentClient.get_code_interpreter_tool(file_ids=["file-abc123"])
agent = ChatAgent(client, tools=[tool])

Fixes #4050
