feat: Remove deprecated body fat percentage chart and integrate master chart for report generation

Browse Source 
- Deleted the old body fat percentage chart image.
- Updated report generation to load the new body fat percentage master chart for improved accuracy and consistency.
- Refactored context generation to reference the new chart in the report structure.
