Minor ux updates

[kobexamoh]

I named this "UX updates" but what I meant was "admin-type-updates-that-the-user-doesn't-see" 🥴

All it does is remove the references to the SVG (external link icon) that no longer are used in the code. There was a bit of confusion around the SVG icon so it was replaced with text. As well, there was some JS that was left unused (see the error message here), so that's been removed as well. Finally, there's unused templates that are removed too.

(I was going to bundle the template into this PR but as I'm not sure if it'll be a huge change or not, I'll just make it part of the next one.)
