feat(mobile): add Quick Actions with image-based navigation

- Replace emoji-based menu with image-based Quick Actions grid
- Add 10 Quick Actions: Education, Exchange, Forum, Governance, Trading, B2B, Banking, Games, Kurd Media, University
- Implement navigation for completed features (Education, Swap, Forum, P2P)
- Add "Coming Soon" badge and alert for features under development
- 3-column grid layout with image previews
- Images should be added to shared/images/quick-actions/

Quick Actions Status:
✅ Education → EducationScreen
✅ Exchange → SwapScreen
✅ Forum → ForumScreen
✅ Governance → Home (temp, needs dedicated tab)
✅ Trading → P2PScreen
⏳ B2B Trading (Coming Soon)
⏳ Banking (Coming Soon)
⏳ Games (Coming Soon)
⏳ Kurd Media (Coming Soon)
⏳ University (Coming Soon)

Note: Images need to be added to shared/images/quick-actions/ directory
