feat(srv6)!: replace openlines query with tiny/full node-info API

- routing-protocol JSON API: nodeinfotinyreq/resp returns device name
  only and is never gated; nodeinfofullreq/resp returns external
  endpoints + device name + description, where denyExternalEndpointQuery
  hides only the endpoint list (name/description always answer);
  legacy openlines* wire types removed - upgrade the whole mesh together
- rename misnamed openConnections -> externalEndpoints and
  denyConnection{Query,Broadcast} -> denyExternalEndpoint{Query,Broadcast};
  legacy config keys normalized on load because gson-2.1 lacks
  @SerializedName(alternate=...)
- remove TCP-based KLALBRemoteManagement, superseded by the HTTP API
- dashboard settings follow the renamed keys; update AGENTS.md
