SAK-50666 Samigo prevent opening links from SEB by default

On the Sakai login screen, there are often external links (e.g., to the APAREO page). When accessing the SEB (Safe Exam Browser), this screen appears, allowing users to open links and navigate to Instagram, Twitter, Google, etc. A student could also type a link (e.g., Google) into a short-answer question and open a new tab.

By default, block access to any link outside the platform itself. If a teacher wants to allow specific links, they can configure them using the SEB app.

If a teacher wants to allow specific links, they can configure them using the SEB app.

Why not allow and block using SEB and not Sakai? The approach in this PR just seems opposite of how I think other lockdown browsers work.

If this really does need to go into Sakai, please use a more-specific Sakai property that refers to SEB

At my university, instructors have been using SEB for some time. It’s intended to create a secure environment where students can only access the exam, and nothing else. Instructors, who use Sakai daily, have expressed frustration about having to use the SEB configuration app for something as basic as preventing navigation to external links. That’s why, with this property, institutions that want to disable external link navigation can enable this feature to apply by default.

I'm not sure if this is what you're referring to @ottenhoff . I'll update the commit tomorrow to add a 'seb.' prefix since I forgot to include it.

@ottenhoff I think you misunderstood this, Sakai configures what will be applied to SEB, but that happens during the creation of an assessment in Samigo. The configuration can be applied manually or automatically, this is for the 2nd case. Just to make it easier for teachers.

makes sense. thanks for changing the properties.
