Shows inbound links (who links to this site, via Site::inboundLinks())
with the referring site, source page, and anchor text — paginated
separately from the Pages table via a distinct page-name query param
so both can paginate independently. Also surfaces a simple outbound
link count and a "N backlinks from M referring domains" summary.
Verified against real data: crawled podcastyradio.es (previously only
known as a backlink target from 00podcast.es) and confirmed its detail
page correctly shows that inbound link with the right anchor text.
