Add automatic calculation for D-section result lines (25, 26, 28, 29)

Browse Source 
Enhanced:
- D-section lines are now calculated automatically from other sections
- Line 25: TVA brute due (sum of sections A and B)
- Line 26: TVA déductible totale (sum of section C)
- Line 28: TVA nette due (25 - 26, if positive)
- Line 29: Crédit de TVA (26 - 25, if negative)
- Configuration page skips D-section as it's calculated
- Added explanatory note in configuration
- Result lines show 'Calculated from...' labels
