feat : relation Bovine -> BovineType, support du bâtiment direct et feed étendu

- Bovine.breedCode (string) remplacé par bovineType (FK BovineType)
- Migration : ajout des races manquantes (Aubrac, Croisé, Blonde d'aquitaine), backfill, drop breed_code
- Sync EDNOTIF : auto-création d'un BovineType placeholder pour code inconnu
- Bovine.building (FK Building, nullable) en plus de buildingCase
- Getter effectiveBuilding (case prime sinon building direct)
- Feed XLSX : colonne E optionnelle (code bâtiment), set uniquement si pas de buildingCase
- Front : DTO + colonnes en variant inventory/case via composable, race et bâtiment ajustés
- Excel export utilise bovineType.label
