Fix getCA3LineAmount to prioritize calculated entries over 'No accounts mapped'

- Updated getCA3LineAmount method to handle duplicate CA-3 line entries
- Prioritizes 'Calculated' entries over 'No accounts mapped' entries
- This fixes lines 28 and 29 not displaying in PDF (they were showing 0 instead of calculated values)
- The method now correctly extracts calculated values: D28=357, D29=0
