Chris Parsons ae3366f571 Add FIFA World Cup 2026 support with group stage display and Monte Carlo simulator, fixes #127
- New `groupStageMatches` table for recording group play results (W/D/L, scores, matchday, schedule)
- `computeGroupStandings()` model function: pts → GD → GF → name tiebreaker ordering
- `GroupStageStandings` component showing all 12 groups with standings table and manager column
- Admin bracket UI: group match score entry, per-group standings, "Recalculate Floors" action
- `WorldCupSimulator`: 50k Monte Carlo covering group stage + best-8 3rd-place + knockout + 3rd place game
  - Fuzzy name matching for national team Elo lookup (exact → substring → word-overlap), warns on miss
  - Partial group completion: completed matches replayed with real scores, remaining matches simulated
  - Elo priority: admin-entered sourceElo > futures odds converted to Elo > hardcoded national team ratings
- `fifa_48` bracket template: added Third Place Game round with `loserFeedsInto` on Semifinals
- Scoring rules: distinct 3rd/4th place for `fifa_48` (not averaged), QF losers share 5th–8th equally
- Floor scoring: SF participants guaranteed 4th (provisional), finalized after 3rd place game
- `recalculate-floors` admin action deletes and replays all results from scratch (fixes stale guard bug)
- Unique index on `(tournamentGroupId, participant1Id, participant2Id)` to prevent duplicate pairings
- Batch `findMatchesByGroupIds()` replacing N sequential queries in the sport season loader
- League home mini-standings now shows `actualPoints` (includes floor) instead of `totalPoints` only
- Elo ratings admin page supports World Cup (same bulk-import flow as snooker)
