anti bcf460d2a5 feat(profiler): write ASN + AS name onto attacker rows
Adds asn (int), as_name (varchar 128), asn_source (varchar 16) to
the Attacker SQLModel — direct columns, no _migrate_* helper per
feedback_no_new_migrations_prev1.

Profiler worker now calls decnet.asn.enrich_ip alongside the existing
geoip enrich_ip; both feed the upsert payload. Failure is total — if
either lookup throws or the IP is private/unannounced, the field stays
None and the row still writes.

Both lookups are independent: a CGNAT address can have a country (RIR
allocation) but no ASN (no BGP origin), and vice-versa for unrouted
RIR-allocated space. Storing them separately preserves that signal.
