Add /profile/index endpoint that returns user_rank_match_total_win (stubbed 0)
and user_class_list built from viewer Classes + owned LeaderSkins. Six NUnit
integration tests cover zero wins, all classes present, level/exp/default skin,
leader_skin_id_list population, is_random_leader_skin round-trip, and 401 on
unauthenticated access.
