Pull request overview

This PR implements Floating Action Buttons (FABs) in the admin-settings app and makes the FAB behavior context-sensitive in the files app's spaces overview. The changes consolidate the creation actions for Users, Groups, and Spaces into a single FAB component that adapts based on the current view, following UI/UX consistency requirements from issues #2011 and #2008.

Changes:

• Added FAB extension to admin-settings app with context-aware handler for Users, Groups, and Spaces views
• Made files app FAB context-sensitive: directly creates spaces on the projects overview, shows dropdown menu elsewhere
• Refactored space creation logic into reusable useSpaceActionsCreate composable and added addNewSpace to useCreateSpace
