fix(ios): resolve clipboard and notification issues in ContactQRScanFullView

- Replace useClipboard() with ClipboardService for iOS compatibility
- Fix notification helper initialization timing issue
- Add proper error handling for clipboard operations
- Ensure consistent behavior across all platforms

Fixes clipboard copy functionality on iOS builds where QR code clicks
failed to copy content and showed notification errors. The ClipboardService
provides platform-specific handling using Capacitor's clipboard plugin,
while moving notification initialization to created() lifecycle hook
prevents undefined function errors.

Resolves: iOS clipboard copy failure and notification system errors
