feat(cases): pull 25 new cases (463-487) from stats.gart.io; dossiers, sources, trim

- pull_live_cases.py: merges https://stats.gart.io/api/attacks into the export.
  The feed lacks notes/reports/original_date/has_processed_date, so existing
  records keep their fields; changed values are taken from live (record 188:
  victim, violence_torture, weapons, summary) and new records are appended
  with those four fields null. Previous export kept as
  attacks-export-Gart-website-2026-09-09-before.json; raw feed saved as
  attacks-live-api-2026-09-09.json. Export now has 389 records.
- 25 new dossiers built; 93 linked URL slots fetched (77 fetched, 8 blocked,
  4 thin, 4 video/social); 76 blocks auto-trimmed. Wayback retry for the 12
  failed slots hit archive.org rate limits (429) and is left for a later run.
- Sheet row 252 (the Phuket robbery listed in cases-missing-from-database.json)
  approved as the source for new case 476, which is that event.
- Stale dossier for renamed case 188 removed.
- Detention flag check on the new cases: 479 proposed 0->1 (forced entry plus
  assault), 468 null->0 proposed, 483 and 486 confirmed 0; review file and
  corrections JSON updated. Worklist and README carry the procedure.

verify_all.py PASSES (2776 checks, 389 case files).
