Fix: Vue node/widget positioning and scroll issue (#5441)

* [feat] Refactor overlay compatibility into reusable composable

- Create useTransformCompatOverlayProps composable for centralized overlay prop management
- Update Select, MultiSelect, TreeSelect, and FileUpload components to use composable
- Provides appendTo='self' for transform inheritance in CSS-transformed parents
- Enables easy future additions of other transform compatibility props
- Fix duplicate v-bind attributes by combining props into single computed object

* fix: Keep the canvas container from being scrolled by children

* types: Align the appendTo type with primevue internals

* Update test expectations [skip ci]
