Creates a module group. Returns the created group (same shape as GET /module-groups/{id}). Optionally pass `moduleIds` to attach modules (each module's default version is used). When Module Hierarchy is enabled, writes return 409 Conflict and clients should use /modules/{id}/versions/{versionId}/submodules. Successful responses include Deprecation: true and a Link successor-version header to /api/v4/openapi. Scoped to your integration's institution via Basic Auth credentials.
