feat(catalog): add auto-category wizard with live preview and smart suggestions

- Add AutoCategoryDialog: pick furni (or empty page), suggest caption/icon/layout, live preview
- Add createAutoCategory server action (page + offers in one export) with CatalogKind
- Extend furni search API with interactionType
- Share ShopTile and refactor inline-editor/items-shop-preview to use it
- Add suggestion heuristics (suggestCategoryName/dIcon/layout) with tests
- Add autoCategory translations (en/nl)
