refactor(desktop): 去黑话 + 收基建灯(商业化语言铺开)

把首屏定的"去黑话+精致克制"语言铺到其余页面：
- 顶栏 5 盏基建灯(Gateway/DB/NATS/Milvus/Neo4j)→ 一枚「系统正常」状态点
  (客户不看数据库名；异常时 tooltip 提示项数,顺带缓解窄屏拥挤)
- 知识库:入库阶段标签去实现名(写入向量库/Milvus/Bleve/Neo4j → 建立语义索引/
  全文索引/构建知识关系);检索台「混合召回+rerank」→「在库中搜索」,命中分数
  0.83→83%,"RAG 未配置"→"该库可能为空";图谱去「Neo4j·力导向」
- 运行:流式中→生成中;"token 在此流式呈现"→"回复逐字呈现";忠实→可信度/引用
- 编排节点「检索(RAG)」→「知识检索」,描述去"混合检索"
