Sean Whalen a3d8651b74 Skip caching weak-fallback IP attributions

get_reverse_dns() swallows every DNSException as None, so a transient
PTR lookup failure (timeout, SERVFAIL, socket error) is
indistinguishable from a genuine no-PTR case. When that lands on the
raw-as_name fallback branch (no map match for the ASN domain either),
the weak result was getting cached in the 4-hour IP-info cache —
locking in the misattribution even after the PTR became resolvable.

Observed in the wild: 91.244.70.212 has PTR customer.evolus-ix.com
(which the map correctly classifies as Evolus IX, ISP), but the
user's dataset showed it with source_name = raw as_name and
source_type = null — the signature of a transient PTR lookup
failure that then got cached.

Fix: skip the cache write when the row is in that specific
weak-fallback state (reverse_dns=None AND type=None AND
name=as_name). PTR-backed matches and ASN-domain matches are stable
attributions and continue to be cached as before.
