Font Awesome 6 Issues

[TimWolla]

• The “change sort order” function within members list page still is an <a> and has an improper color. It likely should be a <button> instead? #4991
  
• “Unsafe HTML” button in editor is missing the icon:
  
• Comment Buttons look off (with one of them miscolored):
  
• Icon coloring in systemCheck.tpl no longer applied. This makes it impossible to differentiate between "warning" and "hard error".
• Make the “active” bell solid in NotificationSettings. This makes the visual difference between “disabled” and “enabled” clearer, especially since the colored outline is fairly thin. Mockup (middle is the suggested version):
  
• Incorrect icon color for style edit buttons in StyleListPage.
  
• Trophy Icons need to be migrated for FA 6.0 #5079
• Handling of FA brand icons is not great #5040
• acpStyleEditor.css still references FA Icon from CSS #5161
• Incorrect icon color for user buttons in MembersListPage.
  
• Not directly a FA 6 issue, but an issue related to icons: https://www.woltlab.com/community/thread/294971-externalurl-after-font-size-auf-inherit-%C3%A4ndern/
• Pagination:
  
• Odd-looking share buttons:
  
• Not directly a FA 6 issue, but an issue related to icons: https://www.woltlab.com/community/thread/295244-inkonsistentes-design-des-drei-punkt-men%C3%BCs/
• Unify visuals in userMenu: The “Manage Your Account” icon is the only one that is available in a non-solid variant by default. Should all icons be forced to be solid for a uniform appearance?
  
• IconFormField validation is broken #5206

Everything is ticked off, closing here. Anything else can be resolved with dedicated issues (like #5371).
