Wire `format_doc_header` into `render_doc_list`: render the block independently, split block_inner into a 1-row header + list via vertical Layout, and drop the `.block(block)` from the List widget. Remove `#[allow(dead_code)]` from `format_doc_header` now that it is consumed. Add `library_renders_column_header_row` integration test.
