refactor(editor): Refactor nodeHelpers mixin to composable (#7810)

- Convert `nodeHelpers` mixin into composable and fix types
- Replace usage of the mixin with the new composable
- Add missing store imports in components that were dependent on opaque
imports from nodeHelpers mixin
- Refactor the `CollectionParameter` component to the modern script
setup syntax
