+Configurable property panels for page-editor blocks (SDUI). The Studio page editor's block inspector now renders typed, protocol-aligned property fields (editing the block's `properties`) for the minimal SDUI-essential content blocks — `element:text`, `element:image`, `page:header`, `page:card`, `record:related_list` — instead of only the generic `type`/`id`/`className`/`hidden` fields. Previously these properties were editable only via raw JSON.
