fix: Clarify MinIO access credentials in UI

- Update CreateUserDialog labels to show 'Username (Access Key)' and 'Password (Secret Key)'
- Add helper text explaining these are MinIO credentials
- Enhanced success display to show credentials with proper MinIO terminology
- Add MinIO CLI connection examples in credential displays
- Fix confusion about where to get access key and secret key

This addresses user feedback about unclear credential terminology and aligns
with MinIO documentation where username = Access Key and password = Secret Key.
