Subject: [PATCH] fix(conf): fix meta-externalagent UA case and use ASN
 verification

The actual User-Agent string is lowercase "meta-externalagent", not
"Meta-ExternalAgent". Since UA matching is case-sensitive, the bot was
not being detected.

Also switch from RDNS to ASN 32934 (Meta) verification for faster and
more reliable detection.
