feat: 朗读脱离提示开关改为双态语义，默认关闭

- 开关语义调整：开启时朗读位置脱离当前页显示「回到朗读位置」悬浮条；
  关闭（默认）时手动翻页后朗读跟随新页面（不脱离、不显示提示条）
- ReadBook 手动导航改为双态处理：开启=脱离，关闭=保持跟随并在翻页后重启朗读到新位置
- 默认值改为 false（ReadSettings/ReadConfigUiState/ReadBookUiState/读方向映射）
- summary 文案更新四语言，ReadSettingsMappingTest 样例同步
- 顺带删除引用已移除类的 DictHtmlParserTest（82d4e4e00 删类未删测试，阻塞测试源集编译）
