Enhance logging functionality and update report generation scripts

- Improved safe_log function to include timestamps and conditional logging
- Added diagnostic messages for field visualization processing
- Updated CI map rendering parameters for consistency
- Refined raster mapping functions in report_utils for clarity
- Added .png files to .gitignore

python_app/.gitignore
