End-to-end tests for DAST on-demand scans and DAST profiles

We currently have no E2E coverage for DAST on-demand scans and DAST profiles management.

Let's think of a few e2e scenarios to be implemented.

A few ideas:

• Running an on-demand scan with a valid profiles combination.
• Unable to run a scan with an invalid profiles combination.
• Creating a new site/scanner profile.
• Editing a site/scanner profile.
• Deleting a site/scanner profile.
• Validating a site profile.
