fix(message-box): resolve auto-close not working for success message

- Add configurable `messageAutoCloseSeconds` setting (0-60s, default 5s) to auto-close the commit message success dialog
- Implement `showAutoCloseMessage()` helper function to display messages with automatic dismissal after specified timeout
- Update success message UI to use auto-close behavior, supporting both managed and feedback modes
- Display countdown hint in message text to inform user of auto-close delay
