fix: SQL maker creates wrong categories and badge import fails when ExternalTexts.json missing

- writeSqlMigration now classifies furni via classifyFurni and generates
  correct category sub-pages (imp_<catKey>) instead of hardcoded imp_other
- writeSqlMigration generates idempotent INSERT...SELECT WHERE NOT EXISTS
  for parent and category catalog_pages, with correct numeric page_id
- writeBadgeToExternalTexts creates ExternalTexts.json (and parent dirs)
  when missing instead of failing with ENOENT
