Update configuration files for Langfuse integration and logging enhancements

- Change LANGFUSE_HOST to LANGFUSE_OTEL_HOST in stack.env for OpenTelemetry compatibility.
- Update litellm_settings.yaml to use the "langfuse_otel" callback for improved logging.
- Remove unnecessary callback settings from general_settings.yaml.
- Add extensive session logging data to status_line.json for better tracking of session activities.
