Ranks the 12 third-placed teams across groups (Pts -> GD -> GF -> id) and marks the top 8 that advance to the R32. Full-width section below the group cards in the Grupos tab, gated on all 12 groups finished (omitted from the DOM otherwise). Reuses .standings-table styling, header tooltips and the favorite-row highlight: gold rows + check for the 8 qualified, muted rows for 9-12, a dashed cut line between. computeThirdPlaceRanking() only ranks for display; the slot->group allocation stays in bracket-config.json. Bumps APP_VERSION to v1.0.3 (also covers the hero knockout-resolution fix).
