修复: CR-28 knowledge error 通道接 Knowledge.vue banner+create 语义修正

knowledge.ts create() 改直接 listCandidates 绕开 loadCandidates 的 state.error 污染,失败 console.warn 非阻塞(保 create 成功语义纯净,原 loadCandidates 失败塞 error 与 create 返回 record 成功矛盾)+加 clearError action 导出;Knowledge.vue 加 error banner(v-if store.error + ✕ 关闭按钮 clearError)让加载/检索/配置失败对用户可见(原 state.error 全应用零消费只看空白列表)。批10 w8orghove,vue-tsc 0
