Bootstrap - UX - Layout config

In Studio Designer, we want a way to copy layouts for efficiency purpose

Typical use case:

• Create creation layout
• Copy creation layout to edit / import / possibly view or metadata

From a tech perspective, note that devs might say we can't copy from create / edit / import to view or metadata (at least for a start) because that means putting the elements in read mode, which is a different code to generate and means more logic.

We need UX / UI mockups for this.

For efficiency purpose we want to let users configure all layouts

• for a given doctype
• for all tasks of a given workflow
• for the form and results layouts of a page provider
  at once.

Ideally we could do that directly from Modeler to avoid back and forth config.
It could also make sense to allow generating on an even larger scale, for a wider selection of various features.

Potential limitation is performances and ability to trigger this from server side (currently handled client side only)

We need a UX / UI for this. Current behavior attached.
