CarterPerez-dev ac334b14f9 feat(canary): geoip wrapper package + config wiring
- internal/geoip: Service over oschwald/geoip2-golang v2 with City db
  enrichment (Country/Region/Subdivision/City) and a NopService
  factory for environments without the mmdb file. Nil-safe Lookup
  returns a zero geoip.Lookup on any failure path (nil receiver,
  nil reader, empty/malformed IP, reader error, !rec.HasData).
- internal/geoip: unexported cityReader interface allows whitebox
  fake-based unit testing without bundling a real .mmdb fixture;
  extractLookup is a pure function for synthetic-record coverage.
- config: GeoIPConfig{Path} koanf section; GEOLITE_PATH env binding
  matching compose.yml; default /data/GeoLite2-City.mmdb.
- deps: github.com/oschwald/geoip2-golang/v2 v2.1.0.

ASN/ASNOrg fields are reserved on geoip.Lookup but stay zero with a
City-only mmdb; populating them is a future-extension concern (ASN
db is not fetched by scripts/init.sh per design §12.5).
