- Added comprehensive field naming documentation (CA3_FIELD_NAMING.md)
- Implemented PDFTK-based PDF form filling with FDF generation
- Added PDFTK installation guide for Linux/Mac/Windows
- Enhanced PDF generation with company data integration
- Added new CA-3 lines: F1, F2 (intracom acquisitions), E1-E6, F6-F8, line 18
- Updated section structure: merged Section C into Section B as sub-section
- Added lines 19, 20 to TVA DÉDUCTIBLE sub-section
- Updated all field descriptions to match official CA-3 form
- Improved visual hierarchy with dark blue section headers
- Enhanced calculation logic for VAT deductible amounts
- Added comprehensive language translations
- Updated database schema with new fields
- Fixed font settings to use Courier New 9pt for official documents
Database Schema Fix:
- Fixed unique constraint to allow multiple accounts per CA-3 line
- Changed from (entity, ca3_line) to (entity, ca3_line, account_code)
- Added migration script to update existing tables
- Updated table comments to reflect new CA-3 line structure
Debug Features Added:
- Database operation logging in updateAccountMapping method
- Table existence and structure checking in setup page

- Form data processing visibility
The issue was likely the unique constraint preventing multiple accounts per line!
