Forms Module Improvements - Duplicate fields and groups (AM-I-723, AM-I-691)

Problem: Recreating similar structures is time-consuming.

Actionables:

• Add “Duplicate Field” and “Duplicate Group” actions.

• Auto-generate unique IDs and detach data bindings safely.

• Include/option to duplicate rules, validations, visibility conditions.

Success criteria:

• Duplicates appear adjacent, preserve settings, and do not break existing logic.

Context: This proposal is part of the broader storyline AM-I-856.
