Studio exports now preserve the specific type of actions instead of treating them as generic actions. This makes exported customizations more accurate and easier to reuse, with only minor related test and cleanup updates.

Signing boxes that do not require action are now hidden, reducing clutter during document review and signing. Boxes also show the responsible person's name, making it clearer who needs to complete each required field.

- Hide sign item box when you don't need to fill it
- Add responsible name to box
