Improve file links from the Merge Request Security Widget

Links to file are taking a lot of space in the Security Widget:

What do you think of removing the links here, and replacing them with a hover link (I think we have an icon like [ ]->)? It should point directly to the diff of the MR, instead of the file in a new window. We already have a link to the file in the modal. Leaving the page when using these links is breaking our idea of everything happening in the MR. Since we're in the context of an MR, all the findings are related to code change. It makes sense to keep the focus in this page.

I’m (just a bit) worried about having multiple similar findings (which would differ only from their location).
