Fix MLB simulator: use projected wins for playoff seeding + perf + cleanup
- Replace hardcoded FanGraphs p_div/p_wc draws with Binomial regular-season
  simulation so that admin-entered projected wins drive playoff qualification
  odds, not just in-bracket game win probability
- Add getRegularSeasonStandings call so mid-season current wins feed into
  projected final standings
- Use normal approximation (Box-Muller) in sampleBinomial for n≥30: drops
  seeding phase from ~243M to ~3M Math.random() calls per 50K-sim run
- eloToRDif now calls rawWinRateFromElo instead of inlining the same formula
- Warn when recognized teams lack a standings row during mid-season simulation
  (silent wrong seeding result with no diagnostic previously)
