fix: ASN dictionary pipeline + verbose bot-detector logging

- Fix dict_iplocate_asn: remove non-existent org/domain columns (4→4 cols)
- Add CSV header to iplocate-ip-to-asn.csv (CSVWithNames format)
- Replace org/domain dictGet calls with empty string literals in MV
- Full 714K CIDR stub for complete ASN resolution in tests
- Add header generation to generate_asn_data.py
- Verbose bot-detector stdout: data summary, triage breakdown, model
  training details, scoring stats, browser classification, boxed results
- Fix IPv6 filter in traffic seeder (_ips_from_cidrs)
