The previous ensure_fields helper used python3 which is not available in alpine:3.19, causing exit 127 in the cloud init container. Replaced with ensure_field (per-field, no python/jq) that uses only busybox sh, wget, sed, and awk. Also fixed the HTTP status grep pattern in create_collection and ensure_field to match only the response header line (^ HTTP/) instead of the wget error line, eliminating the spurious 'unexpected status server' warnings.
