/**
 * Acceptance: API Manager dynamic provider model permissions
 *
 * Confirmed examples (traceable rules):
 *   R1 Legacy empty allowedModels remains allow-all unless explicitly marked restricted.
 *   R2 Explicit restricted mode with zero provider/model selections is deny-all.
 *   R3 allowedModels ["ollama-cloud/*", "openai/gpt-4.1"] allows every current/future
 *      ollama-cloud/... model + that exact OpenAI model; denies unselected providers.
 *   R3b Namespace boundary: ollama-cloud/* must NOT match ollama-cloudx/model.
 *   R4 Selecting provider ollama-cloud saves canonical ollama-cloud/* (not snapshot IDs);
 *      children are inherited/non-individually-toggleable; reopening restores provider scope;
 *      manual exact selections from other providers coexist; alias-prefixed catalog IDs
 *      (e.g. ollamacloud/llama3 with owned_by ollama-cloud) map via canonical provider id.
 *   R5 Management PATCH persists explicit modelAccessMode ("all" | "restricted").
 *
 * Public shape under test: modelAccessMode: "all" | "restricted".
