Summary
Allow admins to duplicate a Library folder from the admin interface.
Problem
Teams often reuse the same folder structure (seasonal campaigns, mirrored org branches). Creating folders manually is slow and error-prone.
Proposed behaviour
- Duplicate folder action on a folder (context menu or row action) in Library admin.
- Options where feasible: duplicate folder only (empty), or duplicate including child folders and assets, with clear labelling and progress for large trees.
- New folder name defaults to Copy of [name] with inline rename.
- Preserve or clearly reset ordering/metadata per product rules.
Draft acceptance criteria
- Admin can duplicate a folder without breaking navigation or permissions.
- No silent overwrite: unique names within parent or explicit collision handling.
- Success and error feedback in the UI.
