feat(resources): add critical CMA logo template file

CRITICAL FIX:
- CMA template (template/CMA_Logo.png) was not tracked in git
- .gitignore had '*.png' rule that blocked all PNG files
- This template is essential for CMA number extraction via template matching

CHANGES:
- Modified .gitignore: Removed '*.png' rule
- Added template/CMA_Logo.png (25KB CMA logo template)
- Added specific ignores for debug/visualization PNGs only

WHY THIS MATTERS:
- CMA template matching is PRIMARY method for CMA extraction
- Without this file, template matching fallback fails
- File used in: test_accuracy_batch_full.py line 138
- Path: CMA_LOGO_PATH = Path("template/CMA_Logo.png")

USAGE:
- Used by match_cma_template() function
- OpenCV template matching with cv2.TM_CCORR_NORMED
- Fallback when primary CMA extraction fails
