"""应用与主窗口装配。

本文件只负责把窗口、导航和页面拼起来，不写业务逻辑。

改动本文件前必读 `client/AGENTS.md`。以下几条最容易踩：

- 图标一律用 `FluentIcon`，**不得使用表情符号充当图标**。
- 不得在这里发起 Admin 请求、SQLite 长查询或 uiautomator2 调用，
  这些会卡死 Qt 主线程。业务事件放到各页面的 `*_ui_event.py`。
- 页面的 `objectName` 必须唯一且稳定，改名会破坏导航。
- 用布局和伸缩项排版，**不要用固定坐标**。
- 不要用全局 QSS 覆盖 Fluent 控件；局部样式必须保留悬停、按下、
  焦点和禁用四种状态。
- 需要文件路径时走 `data_dir()` / `app_dir()`，不要硬编码，
  见 `docs/client/03-data-model.md` §2.2。
