- GET /dns/stats via unbound-control stats_noreset: total queries,
  cache hits/miss, hit-rate progress bar, recursive replies, prefetch,
  rate-limited, unwanted, RRset/msg cache memory
- DNS page: new "Resolver stats" tab with 30s auto-refresh
- NAT rules: ↑↓ move buttons (same pattern as firewall rules 1.1.102)
