Fix translation issues from code review

- Use 'Bénéfice' in French Reports.php for consistency with 'profit' key
- Fix Italian grammar: 'Il numero di telefono è richiesto'
- Use 'Responsabile' for 'manager' in Italian Common.php
- Add 'sale_not_found' translation key to missing languages (km, ml, ta, ur)
- Tamil (ta) gets proper translation, others get English fallback
