fix: include deletion metadata in user API keys response

- Add isDeleted, deletedAt, deletedBy, deletedByType fields to getUserApiKeys service method
- Include deletion fields in user routes API keys response
- Add debug logging to dashboard component to troubleshoot deleted keys count
- Ensure frontend can properly identify and count deleted API keys

This fixes the issue where deleted API keys count was always showing 0
instead of the actual number of deleted keys.
