Added a link from each opportunity to its latest Find a Tender notice

Opportunities from Find a Tender have a link icon before their title.
Clicking it fetches the opportunity with its releases (the list leaves
them out) and opens its newest release's notice,
www.find-tender.service.gov.uk/notice/<release_id>, in a new tab. The
tab is opened on the click and pointed at the notice when the request
returns, so it isn't blocked as a popup; if the request fails, or there
are no releases, it's closed and a toast says why. Opportunities from
other sources have no link for now, but keep its space so the titles
line up.

The icon is lucide-solid's, added for it at 1.52.0.
