Fix image deletion to remove files from disk

Critical fix for desktop mode:
- Updated deleteSelectedImages() to actually delete image files from disk
- Desktop mode now uses fileManager.deleteImage() to remove physical files
- Added proper category detection (task/consequence) for file deletion
- Enhanced error handling for file deletion operations
- Added different success messages for desktop vs web mode
- Maintains backward compatibility with web mode (storage-only deletion)

Previously:
- Images imported to images/tasks/ and images/consequences/ directories
- Deletion only removed references from localStorage
- Files remained on disk, causing clutter and storage waste

Now:
- Desktop deletion removes both file references AND physical files
- Clean filesystem management with no orphaned files
- Proper feedback about file vs reference deletion
- Robust error handling for file system operations
