The header-stripping test sent a real internal address and an internal
client name as forwarded headers. It now uses 203.0.113.44 (TEST-NET-3) and a
neutral client name, and checks those values for leaks instead. The host
setup guide pointed at the build directory of an old monorepo layout; it is
service/ in this repository.
