Make export dialog buttons equal size

- Change both Share and Save to Device buttons to use ActionStyle.NONE
- This creates two equal-sized buttons side by side instead of primary/secondary styling
- Improves UI consistency and makes both options equally prominent
- Users can now easily choose between sharing or saving without visual hierarchy bias
