Description

Problem

1. Confusing print() statements like "environment variable APPLICATIONINSIGHTS_CONNECTION_STRING not set." appeared as errors but were just informational
2. No log message indicated the server started successfully - only "Starting..." was shown

Changes

azure/ai/agentserver/core/logger.py

• Replaced all print() statements with proper logger.debug() / logger.warning() calls
• get_project_endpoint(): Added optional logger parameter with debug logs showing endpoint source:
  - "Using project endpoint from AZURE_AI_PROJECT_ENDPOINT: {endpoint}"
  - "Using project endpoint derived from AGENT_PROJECT_RESOURCE_ID: {endpoint}"
• get_application_insights_connstr(): Added optional logger parameter, replaced print statements with:
  - logger.debug("Application Insights not configured, telemetry export disabled.")
  - logger.debug("No Application Insights connection found for project: {endpoint}")

azure/ai/agentserver/core/server/base.py

• Added startup success log: "FoundryCBAgent server started successfully on port {port}"
• Pass logger to get_project_endpoint() for consistent logging

azure/ai/agentserver/agentframework/_workflow_agent_adapter.py

• Pass logger to get_project_endpoint() for consistent logging
