Add svxdr: the live-data backend (nodelist + proxy; astmeta/xlink optional), config example, systemd unit, INSTALL section 9

svxdr sources from the internal repo with AGPL headers; install/svxdr.json.example is a plain-reflector layout (reflector 8099 -> proxy 8090 -> nodelist 8098) with CHANGEME secrets and no site values. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
