/**
 * 自定义视图接口（票 14）。
 *
 * <p>平台级第二种偏好，与 {@link ColumnPreferenceController} 同处 {@code /api/preference} 前缀下、
 * 挂 {@code /view} 子路径。权限策略同列偏好：不种子化权限点，ApiPermissionInterceptor 对未注册 URL
 * fail-open。视图为用户私有，userId 从 SecurityContext 获取，不接受前端传入。</p>
 *
 * <p>scope 由业务方约定（商机销售机会工作区本期传 {@code opportunity.sales}）；内置视图不走本接口
 * （内置口径硬编码在业务方），本接口只管理用户自建视图。</p>
