Replace strings.Split loops with strings.SplitSeq iterators in the CSV
parsers (reality_scan and the scale-test helpers) and swap a manual map
copy for maps.Copy in the MTProto traffic collector. No behavior change;
these are the fixes the modernize analyzer reports.
Replace the static reality-targets list with a server-side TLS 1.3 probe that checks TLS 1.3 + HTTP/2 + X25519 + a trusted certificate.
- Single-domain validate auto-fills target and serverNames from the cert SAN
- Discovery scans an IP/CIDR without SNI to find new targets from their certificates, deduped and ranked by feasibility then latency, private-IP guarded via netsafe
- New endpoints scanRealityTarget and scanRealityTargets with RealityScanResult, plus openapigen and api-docs entries
- Add scanner strings to all 13 locales
- Replace deprecated AntD Alert message prop with title across the panel
