Adds the first phase of stage-to-stage advancement: a cross-group ranking of the teams finishing just below the automatic qualification spots (e.g. the best third-placed teams), opt-in per stage via config.best_placed_count. - BestPlacedCalculator ranks each group's Nth-placed row across groups by points, goal difference, then goals for (h2h is meaningless across groups, matching FIFA/UEFA cross-group rules) - Stage page shows the ranking with a qualifying cut-line when enabled - Create/Edit stage forms gain "Advance per group" and "Best-placed qualifiers" fields for grouped formats - Ranked position derives from advances_count + 1 (default 3rd) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The best-placed ranking card sits below all the group tables, so an admin enabling it saw no visible change in the standings themselves. Group tables now draw World Cup style qualification zones: - top advances_count rows (automatic qualifiers): volt highlight - the best-placed candidate row: amber highlight - zones only appear when the stage sets advances_count, so tables without a qualification cut keep the plain leader highlight Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Summary
Phase ① of World Cup–style advancement: a cross-group ranking of best Nth-placed teams (e.g. the third-place table used by the World Cup, Euro, and AFCON to fill knockout spots), opt-in per stage via
config.best_placed_count.BestPlacedCalculatortakes each group's Nth-placed row (computed by the existing per-group standings calculator, so in-group tiebreakers incl. head-to-head still apply) and ranks them across groups by points → goal difference → goals for → name. Head-to-head is deliberately excluded across groups — the teams never met — matching FIFA/UEFA cross-group rules.best_placed_countis configured.advances_count) and Best-placed qualifiers fields for grouped formats.advances_count + 1(default 3rd). Groups too small to have an Nth place are skipped.Next phases (separate PRs): entrant slot descriptors on knockout stages,
