Regions control for Krea 3 Edit, and full parameters on imported models

Krea 3 Edit on fal supports regional editing (a regions list of labelled bounding boxes, plus regional_edit to keep pixels outside them unchanged), but Weave doesn’t expose either, on the built-in Krea 3 node or on an imported krea/v3/edit.

The parameters work through Weave’s run pipeline when they’re included, so it looks like a UI gap rather than a backend one. It would be great to have a box editor on the Krea 3 node, and more generally for imported models to show array and object parameters, or offer a raw JSON field, so we get every control the model has.

We use Weave on a team plan for architectural visualisation, and this would make precise local edits to renders much more practical.
