feat(db): moments_post 表+upsert(朋友圈实体,PK=云客data.id,create_time统一ms)

- MomentsPost 模型:moments_post 表,PK=id(云客 getFriendsterInfo data.id),
  wechat_id/create_time 建索引,praise/comment/image 存 JSON 列
- 迁移 524da8d2d597(手写 create_table,已应用到 smoke.db 并在临时 SQLite
  全链路 upgrade/downgrade 验证)
- repos.upsert_moments_posts:批量幂等 upsert;附带修 _build_column_values
  对 JSON 列表的误 join(标量列 join 保持不变,dept_route 旧测试仍过)
- 修复 3 个 chat_group 旧测试缺 owner_account_id(2026-08-24 复合主键遗留)
- 全套 430 测试通过
