feat(web): add /api/node-info endpoint for on-demand node detail queries

- Expose GET /api/node-info?address=<ipv6> endpoint in KLALBWebServer
- Return local deviceName and deviceDescription immediately for self node
- Perform asynchronous full node-info query (NODE_INFO_FULL_REQ) via
  KLALBRoutingProtocolAPIClient for remote nodes with 3s timeout fallback
