## Summary
- Update all illustration icons to use `theme.accent.accent3` for fill
and `theme.accent.accent8` for border
- Replaces hardcoded `IllustrationIcon.blue` values with
theme-responsive accent colors
- Icons will now adapt correctly to theme changes
## Test plan
- [ ] Navigate to Settings > Data model > select any object
- [ ] Verify the Relations "Type" column icons use the accent colors
- [ ] Verify the Fields "Data type" column icons use the accent colors
- [ ] Switch themes (if available) and verify icons adapt accordingly
