feat(stats): final ranking 1-48, favorite highlight, team records (Stage C)

- Canonical final ranking: each team carries a .rank from the stage-reached
  chain (champion>runner-up>3rd>4th>QF>R16>R32>group, then pts>GD>GF>id),
  computed from REAL knockout results only (simulation never moves it). The #
  column shows this rank and is the default sort; it stays canonical when
  sorting other columns, and clicking # returns to it.
- Favorite-team row highlight (gold inset border + tint); re-renders on
  favchange. No stars in the table (highlight-only, like the bracket).
- Team record cards: biggest win (-> openMatchModal), longest win streak
  (>=2, else hidden), and champion's path (R32->Final route, gated on the
  verdict, rows -> openMatchModal). Each degrades away when its data is null.
- stats.js imports getFavorites (storage) + openMatchModal (modal). i18n
  tip.rank/stats.rankCol/biggestWin/winStreak/championPath (EN/PT); CSS for
  .row-fav, record cards, champion path.
