Fixes certain broken icons in the outfit editor, stripping menu and multiple others (#93319)

## About The Pull Request

``icon2base64`` does not like animated icons and will display an atlas
in TGUI when one is passed into it

<img width="239" height="220" alt="JKneqDL9NH"
src="https://github.com/user-attachments/assets/47e0ffdf-c155-4c84-94ce-c23203281012"
/>

Additionally added some padding between the icon and the slot name in
the outfit editor because it annoyed me
