/**
* 权限指令
*
* 用法：
* <el-button v-hasPermi="'park:park-lot:create'">新增</el-button>
* <el-button v-hasPermi="['park:park-lot:create', 'park:park-lot:update']">保存</el-button> // 任一命中即可
* <el-button v-hasRole="'super_admin'">超级操作</el-button>
*
* 权限标识命名规范：模块:资源:动作（与后端 @PreAuthorize("@ss.hasPermission('...')") 完全一致）。
* 指令只是「隐藏入口」，真正的鉴权在后端——前端隐藏不作为安全边界。
