feat(neode-ui): launch cuprate tiles on the Cuprate UI companion

cuprate publishes only raw JSON RPC (18090 restricted, 18183 p2p), so
launches must land on the companion on :18091, never on the running
node's runtimeUrl — same root-path special-case bitcoin uses, with the
dev vite proxy for /app/cuprate-ui/. Alias cuprate -> cuprate-ui so the
port-auth lookup finds the gated launch port on HTTPS nodes; pin the
companion icon to the cuprate mark.
