Users must now select from existing templates, which reduces errors and ensures better template management. This change makes the signature workflow more controlled and reliable.

Before this commit, Using the "request signature" option allowed users to create templates on the fly, which could lead to errors.

In this commit, the Creation of templates on the fly from the wizard is no longer allowed.
