A challenge's win counter is not trophies

In a Classic Challenge, a 20-Win Challenge and other event runs, the game reports the run's win counter where a ladder battle reports trophies. A standout sitting's best_win now rates only wins whose trophies are a real standing (Trophy Road, Path of Legends, the seasonal Trophy Road), so its opponent's starting_trophies is always trophies, and a sitting's trophy_net_by_mode no longer counts a challenge's +1 a win (Timeline).
