refactor(style): 统一项目代码风格，整理导入顺序、间距规范与方法排列

- GUI 模块统一 QtCore → QtGui → QtWidgets 导入排列，各类独占一行按字母排序
- 统一类间两空行、类内方法间一空行、函数间一空行的间距规范
- 统一方法排列顺序：__init__ → setupUi → connectSignals → public → Slot → private
- 统一 _widgets 中 ConditionRowFrame/ActionStepFrame 方法命名（populate* / toScript / updateValueWidget）
- LibTimeSelector 迁入 operators/abs 抽象层
