Tool contract 11.18.7

A sitting's trophy facts on the timeline no longer read a challenge's win counter as trophies (feedback #384). In a Classic Challenge, a 20-Win Challenge or another event run, the game reports the run's win counter as starting_trophies (1-10) and +1 a win as trophy_change; only Trophy Road, Path of Legends, the seasonal Trophy Road (event content under the Ladder ruleset), war and casual rows carry a trophy standing there.

• elixir_timeline (session_standout, battle_session): best_win rates only wins whose trophies are a standing, so best_win.opponent.starting_trophies, trophy_change and trophies_after are always trophies; a sitting whose only wins were challenge or tournament wins has no best_win, as a sitting with no rated win never had. trophy_net_by_mode leaves a challenge's +1s out, so a Classic Challenge sitting no longer shows an event net.
