Refactor CollectingErrorsTest: remove deprecated APIs and clean up exception handling

- Replace deprecated fail() calls with AssertJ assertions
- Fix deprecated catchThrowableOfType() parameter order (Class, lambda)
- Remove unnecessary throws Exception declarations from 27 test methods
- Keep throws Exception only for tests using try-with-resources

All 31 tests pass successfully.
