Classify reverse DNS map: ~2,100 unmapped MMDB ASN domains; bankonitusa.com → Navanta (#751)

Browse Source

Adds ~2,125 ASN-domain classifications carried out across four ~1,000-domain
batches in a prior session that wasn't pushed before #748/#749 merged. The
overlap with those merged batches is dropped — origin/master's classifications
are kept as authoritative — and only the genuinely-new domains land here.
188 known-unknown rows are promoted out to the map for the same reason.

Also updates bankonitusa.com from BankOnIT to Navanta and adds navanta.com as
an alias after a spot check observed the operator's "now Navanta" rebrand
banner. Two corroborating sources: the banner on bankonitusa.com itself
(image-only `<a href="https://navanta.com/brand-launch-..."><img alt="Brand
announcement"></a>`) and the rebrand explainer on navanta.com ("Why We Became
Navanta", "MyBankonIT has been rebranded to MyBPC"). The MMDB still names the
pre-rebrand entity (BankOnIT, L.L.C.) — typical years-of-lag pattern.
