### NEW-0627-1: Catalog product properties — read and manage the property schema

Added the [/v1/catalog-product-properties](/docs/entities/catalog-product-properties) section — definitions of a trade catalog's custom properties (id, name, type). List, get, create, update, delete, search, and the field reference are supported. A product's list-type properties come back in [/v1/catalog-products](/docs/entities/catalog-products) as fields named `propertyNNN`, where `NNN` is the property id. The new section maps that id to the property name and type. The `filter[iblockId]` filter scopes the selection to one catalog, with the id taken from [/v1/catalogs](/docs/entities/catalogs). Requires the `catalog` scope.
