ux: add custom result dialog with visual success/failure icons

- Add ResultDialog class with green checkmark (✓) for success
- Add red X (✕) icon for failure/partial failure
- Center result dialog on screen
- Use color-coded backgrounds (green/red) for better visual feedback
- Replace standard messagebox for more intuitive result display
