Pull the duplicated pagination footer into a single shared component at
frontend/src/components/ui/table-pagination.tsx. Both the desktop
DataTable (which had an internal DataTablePagination driven by a TanStack
table instance) and the Media mobile card list (which had a standalone
MediaMobilePagination driven by raw PaginationState) now consume it.
The shared component takes the raw primitives (pageIndex, pageSize,
pageCount, totalRows, pageSizeOptions, onPaginationChange, optional
className) so it backs both an adapter view (DataTable extracts state
from its table instance and passes table.setPagination) and a direct
state view (Media passes its pagination state directly). Includes the
44px mobile-touch-target on prev/next buttons (previously only on the
Media mobile variant).
Removes ~90 lines of duplication across data-table.tsx and Media.tsx;
adds the focused 122-line shared component. The DataTable Select imports
are dropped (now unused). 122 tests pass; lint/build green.
