feat(editor): Add option to disable NDV in workflow previews (#7990)

## Summary
This PR adds a new property to the `WorkflowPreview` component that
controls if the Node Details View can be opened in each workflow preview
or not.
This property is passed on to underlying `iframe` via the `postMessage`
and is used to disable pointer events for nodes and stickies in that
preview.

#### How to test the change:
Until the component that uses this flag is implemented this can be
tested manually. In this example, we'll use `WorkflowPreview` as part of
the `TemplatesWorkflowView` component
1. Pass `:canOpenNDV="false"` to this component
2. Run n8n
3. Open any template preview and check if nodes and stickies are
interactive
4. Open any workflow execution preview -> Nodes and Stickies should be
interactive

## Issues fixed
Fixes ADO-1548
