fix: corrige les dépendances mobile et la qualité du code frontend

Mobile (Expo SDK 53) :
- supprime victory-native et react-native-svg (dépendances mortes, non
  importées) qui empêchaient l'installation (ETARGET sur svg@~16.0.0 +
  conflit de peer reanimated/skia)
- ajoute les peers manquants expo-constants et expo-linking (requis par
  expo-router)
- aligne expo-router, react-native et react-native-screens sur le SDK 53
- ajoute package-lock.json (installs reproductibles)
- expo-doctor 18/18, tsc sans erreur

Frontend (Next.js) :
- EmotionChart : remplace 4 `any` par les types Recharts (ValueType/NameType)
- EditSaisieModal : remplace le setState dans useEffect par l'ajustement
  d'état pendant le rendu (pattern recommandé par React)
- tsc, eslint et build de production sans erreur

Backend : 15 tests passent (Auth, Admin, Tracker, RGPD).
