Update IAM Service E2E tests and audit plan

- Marked E2E test tasks as completed in the IAM Service audit plan for better tracking.
- Enhanced E2E tests by mocking the Prisma client and its methods to simulate database interactions.
- Improved test coverage for feature creation, update, and deletion operations in the E2E tests.

These changes aim to streamline testing processes and ensure accurate simulation of service behavior.
