Enhance test coverage for IAM module by validating all required fields in response DTOs

- Added assertions to check for non-empty fields in TokenDto, UsersSchema, PermissionsSchema, and RolesDetailItemDto.
- Ensured that all necessary fields are validated in team-related DTOs, including TeamsCreateResponseDto and TeamsDetailResponseDto.
- Improved checks for user details in UsersDetailItemDto and UsersListItemDto to ensure data integrity.
- Verified that sensitive fields are present in admin team responses and member details.
- Updated tests to ensure that created and updated timestamps are present and valid across various entities.
