feat: Feature 1.5 — Bet Submission with 3 methods + performance tracking

Three submission methods: - POST /api/bets/quickslip — structured bet entry - POST /api/bets/screenshot — stub OCR with confirm flow - POST /api/bets/sync — coming soon stub Full bet lifecycle: - PATCH /api/bets/:id/settle — settle with outcome, recalculates performance - GET /api/bets — list with status/book/pagination filters - GET /api/bets/performance — ROI, win rate, profit (weekly/monthly/all_time) Payout calculator handles straight bets (American odds) and parlays (multiplied leg payouts). Performance service recalculates on each settlement and upserts into performance table. 33 new tests, 221 total (194 Node.js + 27 Python), all passing. All backend features for Phase 1 + Phase 2 now complete. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
