perf(watchos-live): FC poussée en temps réel à chaque échantillon (throttle 2s -> envoi immédiat)

Browse Source 
Le throttle fixe de 2s ajoutait jusqu'à 2s de latence sur /live vs l'app
Exercice native d'Apple (instantanée). Désormais chaque nouvel échantillon FC
est envoyé immédiatement ; throttle léger 0.5s conservé uniquement pour
calories/distance (anti-saturation BLE).
