fix: correct ResourceLimits property names in tests

- Replace maxMemoryMB with maxMemoryBytes and convert to bytes
- Replace maxModulesInCache with maxCachedModules
- Remove invalid onWarning property from ResourceLimits options

These property name mismatches were causing tests to use default limits
and fail to properly configure resource limiters, leading to Jest not
exiting due to unclosed intervals.
