/**
 * Repeater sub-field type validation (issue #1424).
 *
 * The Zod enum guarding `validation.subFields[].type` must stay in sync with
 * `REPEATER_SUB_FIELD_TYPES` (schema/types.ts). It was missing "url" (a
 * documented sub-field type the schema-builder UI offers) and gained "image"
 * together with media-picker support in repeater rows.
