List what an owned node currently shares

Ask the node itself what it shares, and say what this cloud will serve.

Not a projection: this deployment stores no share state (D-P26-H1) other than who else may open a private share, which is …/access-rules (ADR-W9), so the list is one bounded daemon-API read over the tunnel, made server-side because the browser cannot make it — the node-proxy credential is __Host- on the node host and this SPA is on app. (D-HC-7). Two facts are joined onto it from here, because they are the two the cloud owns: whether the account may publish at all, and whether the owner has paused anonymous access.

An offline node answers an empty list rather than an error. Its shares still exist — the daemon holds them — and the card says "offline"; a 502 is reserved for a node that is online and did not answer, which is a fault rather than a state.
