[#FER-27] Fix export inventaire bovin (!54)

Une ligne avec données absentes ou hors plage (date < 1900, n° national vide, dates incohérentes) ne fait plus tomber l'export entier en 500. Try/catch par ligne avec log warning, helper safePhpToExcel pour les dates Excel, garde birth <= arrival pour l'âge à l'entrée.
