feat(external): real-time IP/ASN enrichment service (replaces bgptools)

Replace the bgp.tools WHOIS helper module with a richer ip_enrichment service
that exposes the same network_info / network_info_sync API plus on-demand
helpers (lookup_ip, lookup_asn_name, lookup_asn_country, lookup_asns_bulk) used
for ASN organization, country and IXP enrichment. Update the webhook task and
external package exports to the new module.

Stacked series (6/10): builds on pr/bgp-filtered-flag.

+## IP Enrichment
+
+hyperglass can enrich structured responses with ASN, organization, country, and IXP metadata resolved in real time from [bgp.tools](https://bgp.tools/). This data powers the organization names shown on AS paths and next-hops, and the per-hop detail in structured traceroute.
+
+Enrichment is performed by an internal service that issues bulk WHOIS lookups to bgp.tools; results are cached in-memory for the life of the process. No configuration is required to make the service available — it is enabled per-feature via the [`structured.ip_enrichment`](#ip-enrichment-configuration) settings documented below.
