feat: embedding 配置搬上控制面 — 数据源页可视化配置 + 热更新

embedding 从 env 改为控制面驱动(持久化+可视化)，复用 chat 模型同套范式：
配置控制面泛化为按 kind(chat/embedding)，加 embedding kind。

- shared: 配置 subjects 泛化 sundynix.config.<kind>.get/.updated；bus 方法改 kind 参数
  (RequestConfig/ServeConfig/PublishConfigUpdated/SubscribeConfigUpdated)
- gateway: sundynix_model 加 kind 列(每 kind 唯一激活)+旧行回填 chat；admin 按 kind
  增删改/激活/列表，测试连接 embedding 走 POST /embeddings；main 按 kind ServeConfig；
  变更广播各 kind
- dispatcher: 取 chat 配置(kind 化)
- mcp-go: rag.Engine.SetEmbedding 热更新(RWMutex)；main 取/订阅 embedding 控制面配置
  (覆盖 env)
- admin 控制台: api 按 kind；抽出复用 ModelManager；ModelsPage(chat)+新 DatasourcesPage
  (embedding + 向量/图库占位)；routes 数据源页就绪
- 验证: 全模块 build✓ + e2e PASS + 控制台 npm build✓；live 全跑通——chat(DeepSeek 回填
  kind 仍工作)；mcp-go 不带 EMBED env 启动→控制台配 embedding(百炼)→测试连接✓→激活
  →NATS 热更新 mcp-go→入库+语义检索'存向量的数据库'→Milvus；浏览器数据源页拉到激活配置
