Give the tech radar its own page

/radar (/en/radar, /ca/radar) shows every technology the collective has
placed, by ring: logo, category, what it is, why it sits there, its
website and how many projects use it. The landing's radar summary links
to it.

It is the first listing — a page this site composes rather than one
record's — so resolveRoute learns about those (LISTINGS), and builds
their addresses and hreflang alternates from the same table.

Logos sit on a light tile in both themes. A brand's mark is not ours to
recolour, and Rust's, which is black, would vanish in dark mode.
