refactor: 收敛 factory 模块级副作用并统一 async 路径进度为异步后端

- 将 configure_token_codec/configure_plugin_routes 移入 create_app()，消除 import 期副作用
- runtime 层新增 AsyncCacheProxy/AsyncTTLCache/AsyncProgressHelper，共享 progress region
- search/system/history/scheduler/dashboard 的事件循环路径切换异步进度后端
- 同步进度回调经事件循环提交或线程池执行，避免阻塞事件循环
