Fix ranking filter to search across all pages using full JSON dataset

Embed the complete ranking JSON into the page and replace the DOM-only
filter with a client-side search over ALL_ITEMS. When a filter is active
the grid is re-rendered from the full dataset; clearing filters restores
the server-paginated view. Also adds summary zoom overlay on the book page.
