Server locations: no user threshold

The public projection of a server's place showed only the country for
servers reporting fewer than 10 users. The owner never decided that
threshold: every located server now shows its city, coordinates (0.1°)
and network, and a CDN-fronted one still shows only its CDN, since the
address reached is the CDN's edge. Statistics:PublicCityMinUsers is
gone; the ROADMAP decision on server locations, CLAUDE.md and the
/stargazing explainer are corrected.
