chore: refactor dialog components to simplify header structure

- Removed unnecessary button and icon from dialog headers in AboutDialog, ChangePasswordDialog, CreateAccessTokenDialog, CreateUserDialog, EditUserinfoDialog, and GenerateQRCodeDialog.
- Updated dialog titles to be more straightforward by directly displaying the title text.
- Simplified close button handling in ChangePasswordDialog, EditUserinfoDialog, and GenerateQRCodeDialog by directly using the onClose prop.
- Enhanced Dropdown component to manage its open state internally.
