This update hides the 'suggest next documents' tab within the signing feature from users who are not logged into Odoo. This change ensures that sensitive document suggestions are only visible to authorized personnel, enhancing security and data protection. It aligns with our security protocols for confidential document workflows.

This commit makes the suggestion tab of signing next documents hidden to public users, as they should be logged in to be able to see the next documents to be signed.
