/**
 * Cloud LLM-profile service.

 * Profile CRUD is routed to the org-scoped endpoints
 * `/api/organizations/{orgId}/profiles`, which enforce `EDIT_ORG_SETTINGS`
 * server-side — so a member's mutation is rejected with 403 even on a direct
 * API call, not just hidden in the UI. When the active cloud backend has no org
 * bound (legacy API keys), we fall back to the ungated per-user settings route
 * `/api/v1/settings/profiles`, where there is no org role to enforce against.
 *
 * The two routes share shapes except `get` (org returns `llm`, settings returns
 * `config`) and `activate` (org returns `llm`, settings returns `model`); both
 * are normalized to the SDK profile types below. Neither route exposes secrets.
