Subject: [PATCH] Fix recalculateCA3Amounts() method

Fixed:
- Replaced non-existent getDeclarationInfo() with direct database query
- Fetches start_date and end_date from declarationtva_declarations table
- Proper error handling for missing declarations
- recalculateCA3Amounts() now works without undefined method errors
