feat(settings): 适配 kimi-code 0.42.0 —— 实验 flag 镜像 9→6

- 删除已转正/移除的 4 个 flag：secondary-model（模型池恒开）、
  persistence_minidb_readmodel（改由 [database] 配置节）、remote-control、
  search_worker；env 探测清单同步 11→8
- 新增 notify_user flag（KIMI_CODE_EXPERIMENTAL_NOTIFY_USER，实验性
  Updates 面板，默认关闭）
- 设置页移除 secondary-model 专属卡片与「默认开启」徽章，6 个 flag 统一渲染；
  [secondary_model] 模型池配置逻辑不变
- 残留旧键上游 schema 宽容忽略，无需迁移
