feat(core): the pages of routers and home routers after Java, measured against Java

Routers and home routers start a web server on port 80 with Java's index,
log and routes pages in the project's language (routerPages.ts); the
firewall keeps a log per node that outlives a new start; RIP routes carry
the telling router's public address. TCP counts sequence numbers and
segments in Java's characters, not bytes. RouterWebRun records six stories,
with firewalls now built by ScenarioNetwork. Not taken from Java: its router
server sometimes never listening (a race in setAktiv), and </titel>.
