Merge branch 'hotfix/didacticiel'

Origine du problème (BoxConstraints forces an infinite width / RenderPhysicalShape) :
Hauteur non bornée dans le Positioned :
Lorsque la bulle d'aide était positionnée via Positioned(top: ..., bottom: null), Flutter transmettait une contrainte de hauteur infinie (maxHeight: double.infinity).
Le bouton ElevatedButton calcule son ombre et sa forme physique via RenderPhysicalShape en appelant constraints.biggest ; avec une dimension infinie, Flutter générait une contrainte invalide (BoxConstraints(w=Infinity, 50.0<=h<=Infinity)) et crashait le rendu (ce qui provoquait l'écran gris/noir).
Nids de Row imbriqués dans le pied de la carte d'étape.
Solutions apportées :

tutorial_overlay.dart
 :
Hauteur maximale bornée : _buildTooltip calcule et transmet désormais la hauteur disponible réelle de l'écran (availableHeight) via ConstrainedBox(maxHeight: available).
Bouton moderne Material 3 : Remplacement par FilledButton pour le bouton d'action principale ("Suivant" / "C'est parti").
Structure simplifiée : Aplatissement de la barre inférieure avec un Row unique utilisant Spacer().

full_app_render_test.dart
 :
Ajout d'un test d'intégration complet validant le démarrage de l'application et la navigation étape par étape du didacticiel.

+- **Identité Anonyme & Stats** : Phrase de récupération de 15 mots, hachage SHA-256 du wallet et synchronisation du statut de modération.
+- **Expérience de Tir** : Nouveau flux de calibration, boutons de rotation fine, guidage au premier impact et popup de fin de session avec export IA intégré.
+- **Sauvegarde & Partage** : Export/Import JSON complet des sessions, statistiques et armurerie.
