🎨 Design: Inline site and scanner profile creation

Problem

There is a lot of set-up required for on-demand scans. To create a scan from scratch, a user has to visit three separate screens to actually get the scan running (create a scanner profile, create a site profile, and new on-demand scan).

Proposal

Drawing from #267346 (comment 490235828), we should explore allowing users to create site and scanner profiles inline while on the New DAST scan page.

Notes

• If user clicks Cancel when creating a profile, existing confirmation dialog should appear:

• User should always be able to select a new profile from the dropdown, even if they have already started to create a new profile
