feat(live-reporting): select page vs all pages in bulk download

The header tick now selects the current page (its intuitive meaning). When
the whole page is ticked and more filtered rows exist, a Gmail-style banner
offers "Select all N across pages" (and "Clear selection" once everything
is selected) — so users can grab a page-sized chunk without selecting the
entire project.
