Enhanced failure threshold exceeded tests with individual result assertions

- Added comprehensive individual result validation for map failure threshold exceeded count test
- Added comprehensive individual result validation for map failure threshold exceeded percentage test
- Verified proper status (SUCCEEDED/FAILED), index mapping, error types, and result values
- Fixed TypeScript type assertions for accessing nested result payload structure
- Tests now validate both overall completion reason and detailed individual item outcomes
