/**
 * Cloud provider-connections service.
 *
 * Provider-connection CRUD is routed to the org-scoped endpoints
 * `/api/organizations/{orgId}/provider-connections`, which enforce
 * `EDIT_ORG_SETTINGS` server-side (listing requires `VIEW_ORG_SETTINGS`) — so a
 * member's mutation is rejected with 403 even on a direct API call, not just
 * hidden in the UI. This mirrors the cloud LLM-profile service.
 *
 * Unlike the local agent-server (which returns a bare array), the org list
 * route wraps results as `{ connections: [...] }`; this service unwraps that so
 * callers see the same `ProviderConnection[]` shape on both backends. Individual
 * mutations return a bare `ProviderConnection` on both backends. Neither route
 * exposes the stored key; each item carries `api_key_set` instead.
 *
 * Cloud has no unbound-org fallback here: provider connections are inherently
 * org-scoped, so an org must be bound. A cloud backend without an org id is a
 * programming error rather than a legacy-key case.
