feat: box select frame & children to allow resizing at the same time (#9031)

* box select frame & children

* avoid selecting children twice to avoid double their moving

* do not show ele stats if frame and children selected together

* do not update frame membership if selected together

* do not group frame and its children

* comment and refactor code

* hide align altogether

* include frame children when selecting all

* simplify
