i18n FR + EN :
- home.recentScans : 'Mes plantes récentes' / 'My recent plants'
- map.preview.{title,tapHint}
- myPlants.detail.rename{Title,Subtitle,Placeholder,Save}
- myPlants.toasts.renamed

App.tsx : retire NavigationBar.setBackgroundColorAsync + setPositionAsync
(navigation bar déjà bien gérée par expo-navigation-bar par défaut).

BottomTabNavigator + SettingsScreen : petits ajustements layout.
