 Dans un programme j'ai un exercice qui se compose de 3 series, une mesure a suivre de temps, de répétition et un score. J'ai mis le temps cible à 30, le nombre de répétition à 5. Une fois dans ma séance, je suis sur la série 2/3, temps indiqué à 30 s, j'ai mis Répétitions sur 3 et score sur 5, mais quand je clique sur temriner la série, rien ne se passe

+Décision UX : la flèche de retour doit ouvrir le même état Pause que le bouton "Pause" actuel (pas de "Quitter et sauvegarder" direct, pas de désactivation).
+
+Comportement attendu :
+- Tap flèche retour (AppBar leading explicite, pas la flèche Material implicite) pendant état active ou rest : appelle la même logique que _pause (arrête/suspend le repos si nécessaire, persiste la séance en pause, affiche l'écran Pause).
+- Tap retour système Android (PopScope/WillPopScope) : même comportement, pas seulement la flèche AppBar.
+- Depuis l'écran Pause : choix explicite Reprendre / Quitter et sauvegarder / Abandonner la séance (inchangé).
+- Tooltip/accessibility label : "Mettre en pause". Ne pas utiliser le libellé "Retour".
