Fix cache tests: change max to maxSize for lru-cache v11 compatibility

Fixed compatibility issue with lru-cache v11 which requires maxSize instead of max when using sizeCalculation.

Progress: Reduced test failures from 33 to 7 tests (79% improvement)
- Fixed all cache-utils tests
- Fixed 1 baileys-event-stream test
- Remaining 7 failures are pre-existing issues
