What does this PR do?

Adds the item_list Block Kit block to @emdash-cms/blocks.

This block renders compact entity lists that are richer than fields but less structured than table, such as queues, accounts, imports, plugins, and recent objects. Items support a title, optional description, metadata, badge, short icon text, avatar preview, and nested ButtonElement actions.

Avatar previews are restricted to safe root-relative paths and http(s) URLs. Unsafe preview URLs are suppressed.

Discussion: #904
