fix: apply break-even threshold on player stat profile (2.5.2)

build_leaderboard, player_session_series, and session_breakdown_series
in the player detail and players routes were all called without
league.break_even_cents, so win/loss/even classification always used
the $1.00 default regardless of per-league settings.
