Reorganized model structure by replacing 'object' and 'items' with a unified 'item' model using UUIDs, and moved base model logic into separate files. Updated routes to use the new item model and improved request/response handling. Enhanced user and setting models, added utility functions, and improved error handling throughout the codebase. Also added initial .idea project files and minor admin API improvements.
