Refactor local club geographic criteria with nuanced bonuses

- Fix bug: biggestCountrySize used club instead of country - Add local club detection (>40% threshold) - When local club exists (non-legacy mode): * Local club members paired together: get FULL different-club bonus * Ist vs non-Ist (different clubs): normal bonus * Strangers from same visiting club: no bonus (normal same-club) - Legacy mode unchanged for test compatibility - Add LocalClubTest for local club behavior verification

+/**
+ * Test for local club behavior in geographical pairing criteria.
+ *
+ * When a club has more than 40% of players (proportionMainClubThreshold),
+ * it's considered the "local club" and geographical penalties are adjusted:
+ * - Two players from the local club: no club penalty
+ * - Two "strangers" (not from local club) with same club: half penalty
+ * - Players from different clubs: no bonus (like when threshold exceeded)
