MAC Lookup no longer calls maclookup.app. The five public IEEE registries
(MA-L, MA-M, MA-S, IAB, CID) are a new `oui` dataset row — no key needed,
published as downloaded, refused below per-registry row floors — and
common/oui-db.js answers the longest assignment covering a query, the group
bit masked so a multicast address resolves to the block it derives from.
The country is read off the end of the registered address.
?mac= now takes a vendor prefix as well as a full address (6–12 hex digits,
colon / hyphen / dotted / bare), parsed by common/mac-input.js, which the
form shares. An address no block covers is still answered, with its flags.
The route is gated by requireOfflineData while the registries download at
boot. MAC_LOOKUP_API_KEY is gone.
