Add storage management features and UI components

Implemented new storage endpoints in the API and updated the dependency injection to include storage-related services. Enhanced the frontend by adding storage routes and links in the admin layout, along with new types and localization for storage management. Updated documentation to reflect the new storage features and their usage in the admin interface.
