Frank Cools a08cc30293 Add comprehensive EU transaction handling for CA-3 VAT declarations 
EU Transaction Scenarios:
1️⃣ Incoming EU Invoices (Purchases):
- Supplier invoices HT (no VAT)
- French autoliquidation: 4452xxx (VAT due) + 4456xx (VAT deductible)
- Net effect: zero if fully deductible
- CA-3 impact: Lines 17 (VAT due) + 20/21 (VAT deductible)

2️⃣ Outgoing EU Invoices (Sales):
- Case A (B2B): No French VAT, Lines 05/06 (base HT only)
- Case B (B2C): OSS threshold handling (€10,000)
- Case C (Special): Construction/energy reverse charge
- Invoice text requirements for EU transactions

3️⃣ DEB/DES Integration:
- Link CA-3 lines 05/06 with exchange declarations
- Cross-validation between CA-3 and DEB/DES
- Automatic data import and validation

Enhanced Features:
- EU transaction type detection and classification
- OSS threshold monitoring and alerts
- DEB/DES data integration and validation
- Special case handling (construction, energy)
- Comprehensive EU transaction workflow

Updated estimates: +64 hours for EU transaction handling
Total project: 414+ hours with full EU compliance
