jason 2aa041d45e Milestone 4: payment abstraction, receipts, refunds, logging, hardened Docker

- lib/payments.ts: provider-agnostic payment interface; cash (immediate) and
  card stub (swappable for Square/Stripe Terminal/Tyro)
- POST /transactions/:id/refund — manager+, server-authoritative, blocks double-refund
- GET /transactions/:id/receipt — structured receipt payload for print/email/SMS
- lib/logger.ts: minimal structured JSON logger respecting LOG_LEVEL env var
- middleware/requestLogger.ts: per-request method/path/status/ms logging
- errorHandler now uses structured logger instead of console.error
- Dockerfile: non-root user (appuser), HEALTHCHECK via /api/v1/health,
  npm cache cleared in runtime stage
