fix: review corrections for PR #86

- Remove .codex (Codex CLI artifact, not part of project)
- Restore CHANGELOG.md v0.23.17 entry (was deleted by contributor's fork)
- Restore version to 0.23.17 in package.json and package-lock.json
- Restore native translations for catFood, catLeisure, catEducation in ar, el,
  hi, ja, ru, sv, tr, uk, zh (PR had replaced them with English strings)
- Replace Portuguese seed names in migration 16 with English (housing, food,
  transport, personal_health, leisure, shopping_clothing, education,
  financial_other and all subcategory display names)
