Add oxlint linting setup with zero errors (#194)
* Add oxlint and fix all lint errors

- Install oxlint, add .oxlintrc.json with rules for TypeScript/React
- Add npm run lint / lint:fix scripts
- Add Claude PostToolUse hook to run oxlint on every edited file
- Fix 101 errors: unused vars/imports, eqeqeq, prefer-const, no-new-array
- Fix no-array-index-key (use stable keys or suppress positional cases)
- Fix exhaustive-deps missing dependency in useEffect
- Promote exhaustive-deps and no-array-index-key to errors
- Fix Map.get() !== null bug in $leagueId.server.ts (should be !== undefined)

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* Fix no-explicit-any warnings and upgrade tsconfig to ES2023

- Replace all `any` types with proper types or `unknown` across ~20 files
- Add typed socket payload interfaces in draft route and useDraftSocket
- Use any[] with eslint-disable for socket.io callbacks (legitimate escape hatch)
- Bump all tsconfigs from ES2022 → ES2023 to support toSorted/toReversed
- Fix cascading type errors uncovered by removing any: Map.get narrowing,
  participant relation types, ChartDataPoint, Partial<NewSeason> indexing
- Add ParticipantResultWithParticipant type to participant-result model
- Fix test fixtures to match updated interfaces (DraftCell, ParticipantResult)
- Fix duplicate getQPStandings import in sportsSeasonId.server.ts
