The phone no longer writes estimated Health workouts: the watch, which runs the live session, is the sole recorder. Replaces WorkoutHealthWriter with a WorkoutHealthDeleter that only removes a legacy phone-estimate workout when its record is deleted here, drops the MET calorie table and the phone's write/read Health scopes, and keeps phoneEstimate decodable for existing documents.
