Add a smoke test after deployment

[pamelafox]

Purpose

This pull request updates the Azure deployment workflow with an automated smoke test to validate the deployed chat endpoint. The "Smoke Test Chat Endpoint" step automatically checks the /chat/stream endpoint of the deployed service, retrying up to 6 times to confirm it responds with HTTP 200, improving early detection of deployment issues.

Inconsistent indentation: the uri output should be indented with 6 spaces to align with the outputs: key, not 8 spaces.

Using os.environ directly will raise a KeyError if the environment variable is missing. Consider using os.getenv() with a descriptive error message or add proper error handling to provide clearer feedback when the required environment variable is not set.

Suggested change

	client_id = os.environ["AZURE_CLIENT_ID"]
	client_id = os.getenv("AZURE_CLIENT_ID")
	if not client_id:
	raise RuntimeError("AZURE_CLIENT_ID environment variable is not set but is required for managed identity authentication.")
