feat: SP 监听器替换为 AppConfigStore observe Flow

PR-2: 组B 监听器迁移 —— 删除 AppConfig 的 OnSharedPreferenceChangeListener，
缓存字段退化为 computed get 读快照；WebDavManager/BaseReadAloudService
改用 AppConfigStore.observe* Flow（per-key drop(1) 后 merge）。

- AppConfig: 删除 SharedPreferences.OnSharedPreferenceChangeListener 实现、onSharedPreferenceChanged、syncReadPreferences、syncReadPreferenceFromSharedPreferences、detectClickArea、detectMangaClickArea
- AppConfig: clickAction*/isEInkMode/isTransparent/readBarStyle* 从 var 缓存退化为 val get() 读快照
- App.kt: 删除 defaultSharedPreferences.registerOnSharedPreferenceChangeListener(AppConfig)
- WebDavManager: 删除 SP 监听，改用 5 键 obverseString + drop(1) + merge
- BaseReadAloudService: observeSharedPreferences 替换为 2 键 obverseBoolean + drop(1) + merge
