feat: CSV generation scripts, API filter params, enriched CSV stubs

- scripts/generate_bot_ip.py: download Tor exit nodes + curate scanner IPs (1353 entries)
- scripts/generate_bot_ja4.py: 31 bot JA4 fingerprints across 16 families
- scripts/generate_asn_data.py: 38 ASNs + 96 IP-to-ASN prefixes
- scripts/update-csv-data.sh: master orchestrator with --install-stubs
- api.py: add asn_org/country_code/ja4/bot_name filters on detections+scores
- pages.py: add /network route
- csv-stubs: enriched with generated data (Tor nodes, scanner IPs, etc.)
