* Add playoff match games and odds storage
Introduces two new tables for bracket matchup detail storage:
- `playoff_match_games`: tracks individual game schedules within a
series matchup (game number, scheduledAt, status, per-game scores,
winner). Supports scheduled/complete/postponed status enum.
- `playoff_match_odds`: stores moneyline odds per participant per
matchup (single upsert record, no isLatest complexity).
Includes:
- Drizzle schema + relations with CASCADE deletes from playoff_matches
- Migration 0040_fat_puma.sql
- playoff-match-game.ts model with pure helpers: computeSeriesScore,
isSeriesComplete, getSeriesLeader — plus full CRUD
- playoff-match-odds.ts model with pure helpers: americanToImpliedProbability,
impliedProbabilityToAmerican, normalizeOdds — plus upsert/read/delete
- findPlayoffMatchesByEventId and findPlayoffMatchById updated to
include games and odds in their query results
- Bracket server route: add-game, update-game, delete-game,
upsert-odds, delete-odds actions
- Bracket admin UI: expandable per-match panel for game schedule
management and moneyline odds entry
- 41 new unit tests (18 game + 23 odds), all 810 tests passing

* Code review fixes: type safety, abstraction, and React correctness
- Derive PlayoffMatchGameStatus from schema enum instead of hardcoding
the string union, eliminating the duplicate source of truth
- updateGame now returns PlayoffMatchGame | undefined to reflect reality
when no row matches the ID
- Remove TOCTOU check-then-act in update-game action: call updateGame
directly and check the return value instead of a pre-flight findGameById
- Add status enum validation before the cast in update-game action
- Move impliedProbability computation inside upsertMatchOdds so callers
only provide moneylineOdds; the model owns the derivation
- Remove unnecessary dynamic import of americanToImpliedProbability in
the upsert-odds action (was already imported from the same module)
- Fix React list reconciliation bug: replace bare <> fragment with
<Fragment key={match.id}> so React can correctly track rows
