feat : modal d'export inventaire avec filtres par tranches d'âge

- UiModal : composant générique réutilisable (teleport, escape, backdrop, max-width configurable)
- InventoryExportModal : 3 checkboxes pour les tranches d'âge, footer centré sans annuler
- BovineRepository::findActiveForInventoryExport(?array $ageRanges) en DQL
- Endpoint inventory-export accepte ageRanges (comma-separated) en query param
- Aucune coche = export complet (comportement actuel intact)
