Improve autocomplete UI

I created a merge request where the “throbber” icons have been replaced with Claro’s magnifying glass icons. I also updated the helper text in an attempt to add clarity.

Attaching a patch generated from this merge request.

Updated patch after fixing test.

Composer choked on patch generated from issue fork. Attaching new one that composer liked which was generated using patch utility.

📌 Implement js- prefix for linkit textfields to separate JavaScript behavior from styling Needs review essentially does the same, but without duplicating Claro CSS

Updated patch for latest 7.x

looks good to me!

Nevermind, the latest patch breaks things. The linkit autocomplete isn't used at all with it. Needs some work.

Patch from #8 appeared to have unrelated changes. I just updated the merge request to be compatible with latest from 7.x and hid the patch files.

Please, use MR updates for future updates, not patch files.
