Pull Request Overview
This PR implements a change to trigger afterEntityMutation hooks after database transactions are committed, ensuring proper hook execution timing for transactional operations.
Key changes:
- Modified hook execution logic to defer
afterEntityMutationhooks until after transaction commit - Updated test cases to reflect the new behavior where hooks don't affect database operations when they throw
- Removed obsolete transaction-related test cases that are no longer relevant
