Implement existence checks for various entities in update functions

- Added functions to check the existence of invitation codes, members, OAuth accounts, roles, teams, and user types before performing updates, enhancing error handling and user feedback.
- Updated relevant update functions to utilize these existence checks, ensuring accurate error messages when no changes are made or when entities do not exist.
- Refactored tests to validate the new existence check logic, improving overall test coverage and reliability.
