Groupfolders frontend polish

[Pytal]

From #225 (comment) verbatim:

2 UI aspects that need polishing:

• related resources items should be left aligned not centered
• related resources item icons for a circle is not properly dark/light themed like the other icons/avatars

@Pytal can you take care of this one, priority is higher then A11Y since we would need this for RC1
