feat: move "basic" grid pagination logic to wuttaweb
so far only "simple" pagination is supported by wuttaweb, so basically the main feature flag, page size, current page. in this scenario *all* data is written to client-side JSON and Buefy handles the actual pagination. backend pagination coming soon for wuttaweb but for now tailbone still handles all that.
