feat(exercice): exécution de séance avec module séquence et bips (ticket #60)

Ajoute le lecteur de bips d'étapes (presentation/exercise_step_audio.dart,
port ExerciseStepAudioCuePlayer injectable en test, jamais le vrai
audioplayers en test) et les fichiers audio associés
(assets/audio/step_countdown_short.wav, step_completion_long.wav).
Câble ActiveExerciseStepUseCases dans app_bootstrap.dart et l'expose à
WorkoutExecutionScreen. Les appels audio réels sont protégés par un
try/catch qui log sans jamais bloquer la progression d'étape. flutter
pub get OK (ajout audioplayers), analyze propre (mêmes infos
préexistantes + 2 nouvelles use_build_context_synchronously, non
bloquantes), 100/100 tests verts, build APK debug validé.
