Python: Fix as_agent() not defaulting name/description from client properties

[giles17]

Summary

AzureAIClient.as_agent() and AzureAIAgentClient.as_agent() now fall back to self.agent_name and self.agent_description when name/description are not explicitly passed. This ensures Agent.name is populated for telemetry spans without requiring callers to repeat the name.

Problem

When creating an agent via AzureAIClient(agent_name="my_agent").as_agent(...), the resulting Agent.name was None because as_agent() never consulted the client's stored agent_name. This caused OpenTelemetry spans to record agent_name=None instead of the actual agent name.

Fix

One-line change in each client's as_agent() override:

• name=name or self.agent_name
• description=description or self.agent_description

This matches the pattern already used by AzureAIProjectAgentProvider._to_chat_agent_from_details(), which explicitly passes the same name to both the client constructor and the Agent constructor.

Tests

Added 6 new unit tests (3 per client) covering:

• Default name/description inherited from client properties
• Explicit name/description overrides client properties
• No name set anywhere results in None

All 191 azure-ai tests pass.

Fixes #4471

Pull request overview

This PR fixes a telemetry/observability gap in the Azure AI Python clients by ensuring as_agent() propagates agent_name / agent_description stored on the client into the created Agent when callers don’t explicitly provide name/description.

Changes:

• Update AzureAIClient.as_agent() to default name/description from self.agent_name / self.agent_description.
• Update AzureAIAgentClient.as_agent() with the same defaulting behavior.
• Add unit tests for both clients covering defaulting, explicit overrides, and the “no name set anywhere” case.
