Improve error handling for SSH setup failures in option 3

Instead of exiting immediately when SSH key setup fails, the script now:
- Offers retry option for transient issues
- Allows skipping SSH setup with manual configuration instructions
- Provides option to return to main menu
- Continues deployment flow more gracefully

This prevents frustrating exits when SSH configuration needs adjustment.
