Razvan Dimescu 948372bd67 feat: recursive bar in dashboard, special-use domain interception ...

Dashboard:
- Add Recursive bar to resolution paths chart (cyan, distinct from Override)
- Add RECURSIVE path tag style in query log

Special-use domains (RFC 6761/6303/8880/9462):
- .localhost → 127.0.0.1 (RFC 6761)
- Private reverse PTR (10.x, 192.168.x, 172.16-31.x) → NXDOMAIN
- _dns.resolver.arpa (DDR) → NXDOMAIN
- ipv4only.arpa (NAT64) → 192.0.0.170/171
- mDNS service discovery for private ranges → NXDOMAIN

Eliminates ~900ms SERVFAILs for macOS system queries that were
hitting root servers unnecessarily.
