fix: use dynamic integer range from fcitx5 config properties

Pass IntMax/IntMin properties for Integer type options to QML SpinBox,
enable editable input and set fixed width to prevent layout stretching.

将Integer类型选项的IntMax/IntMin属性传递到QML SpinBox，启用可编辑输入并设置固定宽度防止布局拉伸。

Log: SpinBox支持动态整数范围和可编辑输入
PMS: BUG-357563
Influence: Integer类型配置项的SpinBox现在使用fcitx5配置中定义的实际范围，支持手动输入数值。
