Duplicate records as drafts, and preview them from the form

The copy keeps the content, stack and team, but is unpublished, out of any
review, and gets a title marked as a copy and a free slug. It replaces
Filament's replicate action, which left the copy without a slug and still
published. The same copy is available through the API.
