feat(me,home): 模型推理自检 + 启动容错 + 首页假数据清理

- KangkangApp: ModelContainer 创建失败时重置本地 store 重建,
  避免 demo 阶段 schema 演进导致旧真机启动崩溃(注:生产需正式迁移)
- ModelSelfTestView: 正式的推理自检页(固定 prompt + 流式输出 + tok/s),
  仅当 LLM 模型就绪时从「模型管理」出现入口
- 删除 DEBUG-only 的 DebugAIRunner,自检转正为就绪后可见的正式入口
- HomeView: 删除写死的「今日摘记」假数据卡;问候改为按时段动态
  (早安/下午好/晚上好)+ 当天日期;影像档案数字接真实 @Query 计数
- MeView: 模型管理卡动态状态 + 关于页接真实版本号(用户改动一并纳入)
