Add six base_reverse_dns_map entries from MMDB coverage-gap analysis (#722)

* Cover ASN-fallback path for the Evolus operator family

Only evolus-ix.com (the Internet Exchange product) was in the map,
so ASN-fallback lookups for IPs without PTR fell through to the raw
as_name string with no service type. The bundled IPinfo Lite MMDB
stores the same operator's blocks under two other as_domain values:

- evolus-it.com (the corporate domain, Evolus IT Solutions GmbH)
- evolusfibre.com (their consumer fiber ISP brand)

Both resolve to as_name "Evolus IT Solutions GmbH" in the MMDB,
confirming they're the same operator. WHOIS on evolus-it.com and
the evolusfibre.com homepage both pin the company to Austria. Added
both as aliases pointing at the existing (Evolus IX, ISP) entry so
all three product brands cluster under one display name, matching
the comcast.net / comcast.com pattern documented in AGENTS.md.

* Add aliases for centrilogic, 1gservers, etherni, globconnex

Four additional ASN-domain aliases discovered via coverage-gap
analysis against the bundled IPinfo Lite MMDB. None of the four
brands are currently represented in the map under any key, so these
are new brand entries (not alias-of-existing).

- centrilogic.com → Centrilogic, MSP
  82 MMDB nets, ~62K IPv4. Homepage describes the company as an
  "end-to-end I.T. transformation" managed-services provider.
- 1gservers.com → 1GServers, Web Host
  117 nets, ~23K IPv4. Homepage: bare-metal dedicated servers and
  Phoenix colocation.
- etherni.com → Ethernic, MSP
  2 nets, 768 IPv4. Homepage: cloud-migration / cloud-native
  consulting. Operates its own small ASN under Ethernic LLC.
- globconnex.com → Global Connectivity Solutions, ISP
  687 nets, ~63K IPv4. Homepage unreachable (self-signed cert); WHOIS
  privacy-redacted. Classification is inferred from the MMDB as_name
  "GLOBAL CONNECTIVITY SOLUTIONS LLP" and the routed-network scale.
