- Added image upload system (JPG/PNG, max 5MB) with live preview and removal option
- 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
- Refactored HallOfFameService to use streams for Server/Wasm compatibility
- Improved error handling and UI feedback for upload and delete operations
