Move Load more into the top toolbar; auto-fetch when a delete empties the page master
Two changes to the collection record list: - Relocate the "Load more" control from below the list into the top toolbar alongside Edit and Go live, restyled as a matching chip. - When a delete empties the loaded page while the PDS still has more records, fetch the next page automatically instead of showing a false "No records" / 0-count state. A new effect pulls the next page whenever the list is empty but not exhausted (guarded against the initial load and against spinning on a fetch error). The empty-state placeholder and the record count now key off `done` rather than `loading`, so nothing false flashes in the gap between the page clearing and the refetch.
