- Fixed Concurrency Exception during deletion (split transactions for reports and entries)
- Optimized card layout: consistent height and height-based truncation for descriptions
- Added sort direction toggle (Ascending/Descending) with arrow icons for Date, Name, and Year

- Improved error handling and UI feedback for upload and delete operations
