Compilation .exe PyInstaller + fix chemins resources

- L'installation compile maintenant un vrai .exe autonome
- Les raccourcis Bureau/Menu Demarrer pointent vers le .exe
- Support PyInstaller pour les chemins resources (logo, icone)
- La mise a jour recompile aussi le .exe
- Fallback lanceur .vbs si compilation echoue
