Class CreateInteractiveFormAction

Create a net-new interactive-form override for the requesting user.

Net-new path only. Returns ALREADY_EXISTS if the user already has an Active override for the target entity — agents should call Get Active Form For Entity first and route to Modify Interactive Form in that case. (Pending sibling overrides do NOT block creation — those are an in-flight refinement and Modify will resolve them in-place.)

Security clamp — Scope. This action always writes Scope='User', UserID=ctx.user.ID, Status='Active', Priority=0, regardless of any scope-related parameter the caller might supply. This is the load-bearing safety property of the AI authoring path: an agent cannot write Global or Role overrides that would affect other users. Scope promotion (User → Role → Global) is a separate, deliberate human action in Component Studio / Form Builder dashboard.

Atomicity. If the override insert fails after the Component insert succeeds, we surface PERSIST_FAILED with the Component already in the table. Orphan Components are harmless — they don't render anywhere until something points an override at them. The caller can retry; a second run will create a fresh Component and a successful override.
