feat(utils): 添加 ConfigManager 与 JSON 配置读写，替换旧实现

add:
- src/utils/ConfigManager.py
- src/utils/JSONReader.py
- src/utils/JSONWriter.py
remove:
- src/utils/ConfigReader.py
- src/utils/ConfigWriter.py
refactor:
- 更新调用方以使用 ConfigManager / JSONReader / JSONWriter（见 ALConfigWidget.py、ALMainWindow.py、ALTimerTaskManageWidget.py、ALMainWorkers.py 等）
- 统一方法命名（initlize* -> initialize*）、改进错误提示与配置路径管理

BREAKING CHANGE: 删除 ConfigReader/ConfigWriter，外部调用需改为 JSONReader/JSONWriter 或通过 ConfigManager 访问配置
