perf: add rate limiting, validation, logging, and error handling

- Add express-rate-limit with tiered rate limits per endpoint
- Add express-validator for input validation on all API routes
- Add winston + morgan for structured logging
- Add node-cache for lottery result caching (5min TTL, 1000 max keys)
- Convert OCR to async task queue with max 2 concurrent jobs
- Add global error handler middleware
- Add React ErrorBoundary for client-side error handling
- Fix memory leaks in OCR task queue and lottery cache
- Add per-item error handling in batch ticket updates
- Fix SQL UPDATE to include user_id in WHERE clause
