build(cmake): refactor Qt version compatibility

- Separate debian/control files:
  * control: V25 (Qt6) with explicit qt6-base-dev, libdtk6*-dev deps
  * control.1: V20 (Qt5) with explicit qtbase5-dev, libdtk*-dev deps

This enables seamless building on both V25 (Qt6) and V20 (Qt5) systems
without version-specific conditional dependencies.

Log: 分离Qt5/Qt6构建配置，支持V25/V20双版本
