Marc-André Bombeck 0eac84aa95 fix(geo): read the offline databases first
The resolver queried the online provider first and read the mounted
GeoLite2 databases only when that missed. Every document describing the
feature said the opposite, including the self-hosting runbook and the
admin notification that tells an operator their login IPs are leaving
the server. So an operator who mounted the databases in order to stop
that egress kept all of it, and nothing said so: the location resolved,
the admin overview filled in, and the only difference was where the
address had been.

Now the local databases answer and the provider only ever sees an
address they could not place. A host with the City database mounted and
a hit makes no request at all — including when the ASN database is
absent, because reaching out for a carrier string would send the address
off the host anyway, which is the thing the mount was for.

IP_GEO_LOOKUP_DISABLED=1 remains the full off-switch: it disables the
online step only, so an offline hit still resolves and an offline miss
returns nothing rather than going online.

The wide-event warning on the fallback path named ipwho.is even when the
operator had pointed IP_GEO_LOOKUP_URL somewhere else; it now names the
host the runtime actually queries. The admin notification copy needed no
change — it fires only when the databases are absent, and then every
lookup does go online.

The two cases in geo-asn.test.ts that pinned the old order are the
watched red for this change.
