Add showTotal attribute to GraphIndicator

- Add showTotal attribute to GraphIndicator class with default value True
- Include showTotal in response when processing indicators
- Add comprehensive tests for showTotal functionality in both graph_spec.py and processor_spec.py
- Maintain backward compatibility with default showTotal=True
