Update configuration for the transfer_to_phone tool.

    Allows you to configure:
    - Enable/disable the tool
    - Phone destinations (list of phone numbers with names and availability)
    - Transfer message

    Phone destinations structure:
    ```json
    {
      "phone_number": "+393471234567",  // E.164 format
      "name": "Reception",
      "description": "Main reception desk",
      "available_hours": {  // Optional schedule
        "monday": ["09:00 - 18:00"],
        ...
      }
    }
    ```

    Important:
    - phone_destinations is REQUIRED when enabling the tool (is_enabled=true)
    - Phone numbers must be in E.164 format
