WorkoutKit : étend support strength/core/yoga/HIIT/flexibility + location auto

Mapping HKWorkoutActivityType élargi :
- strength → .functionalStrengthTraining
- traditional_strength → .traditionalStrengthTraining
- core, core_training → .coreTraining (utile pour X Core REHAB)
- hiit, high_intensity → .highIntensityIntervalTraining
- cross_training → .crossTraining
- yoga → .yoga
- pilates → .pilates
- flexibility, stretching, mobility → .flexibility
- swimming → .swimming
- mixed → .mixedCardio

Location auto :
- strength/core/yoga/pilates/flexibility/HIIT/cross → .indoor
- cardio outdoor (running, cycling, walking, hiking, swimming) → .outdoor

→ Permet de pousser des séances strength/core/yoga structurées en blocs
intervalles (60s travail / 15s récup × N) sur l'Apple Watch. Idéal pour
X Core REHAB et autres séances time-based de Sylvain (gainage, holds, circuit).
