/**
 * Service panel descriptors — the handwritten *override* layer of the right
 * sidebar. The sidebar's baseline is the dynamic channel list served by
 * `GET /api/v1/debug/channels` (every wire-exposed Service with its methods);
 * a descriptor here replaces the generic card for its Service with a curated
 * one: a `fetch` that reads its inspectable state and optional `actions`
 * that trigger its methods. The generic `ServiceCard` renders them; adding a
 * curated panel is one entry here, no component code.
 *
 * Panels refresh manually (Load / Refresh buttons): the live event streams
 * that used to drive `refreshOn` refetches went away with the v2 socket
 * (`/api/v2/ws`).
 *
 * The proxies are typed by the real `agent-core-v2` contracts at the call
 * site, but panels treat them as `AnyService` so one descriptor shape covers
 * every Service.
