feat: production-ready zaps with manual close and profile integration

Payment Flow Improvements:
- Remove auto-close after successful payment
- Change "Zap Sent!" button to "Done" button that requires user click
- User must manually close window by clicking Done after payment
- Retry payment also requires manual close after success

Profile Viewer Integration:
- Add Zap icon next to lightning address in ProfileViewer
- Click zap icon to open ZapWindow for that profile
- Yellow icon with hover effect for visual feedback
- Integrates seamlessly with existing profile UI

Production Cleanup:
- Remove all debug console.log statements
- Keep console.error for production error logging
- Remove unused emojiService variable from useEmojiSearch
- Fix Loader2 className typo (animate-spin)
- Clean code ready for production deployment

User Experience:
1. View profile with lightning address
2. Click yellow zap icon to open zap window
3. Enter amount and optional comment
4. Pay with wallet (or QR code if timeout)
5. See success message
6. Click "Done" to close window (manual control)

Testing:
- All lint checks pass (no errors, only warnings)
- TypeScript build successful
- All 939 tests passing
- Production-ready code

Code Quality:
- No debug logging in production
- Proper error handling maintained
- Clean, maintainable code
- Follows project conventions
