feat(17-04): faq:import-winter and the read-only Winter export SQL

- JSON lines import keeping ids, locale_id looked up by locale code (an unknown code aborts before any write)
- one transaction, setval past the copied ids, --force replaces, --dry-run reports, an empty file copies nothing
- scripts/winter-export.sql: SELECT JSON_OBJECT with the translate locale code
- TestFaqImportSmoke
