Fix TypeScript errors from bundlePath to serverBundleCachePath rename in Pro package

Following the rename in the main package, update the Pro package's node-renderer to use serverBundleCachePath consistently:

1. configBuilder.ts: Add null check when using deprecated bundlePath as fallback
2. vm.ts: Use serverBundleCachePath instead of bundlePath for debug file paths

These changes fix TypeScript compilation errors where bundlePath (optional) was being used where a string was required.
