feat: T6 wave 5 – readiness checks and report, compliance and medicine UI, label UI

- Readiness: all 18 checks (medicine lots, treatment log gaps, labels,
  harvest withdrawal), medicine subjects masked without
  veterinary-medicines:read, report PDF (counts only), summary cached 60 s,
  409 codes READINESS_*.
- Frontend: /compliance page with acknowledge/revoke, dashboard line and
  nav; veterinary medicine catalogue, lots, movement book with inventory
  and disposal; label designer check panel, print card with gap list and
  proof print, food business master data, product legal name.
- Service worker: cacheability is path-based (the backend sends no-store
  on every answer); compliance, medicine, restriction, notice and label
  check/print paths and restricted document kinds are never cached.
- ARCHITECTURE.md §2, §12.10–12.11, Annahmen 86–90.
