Fix worker.ts to use serverBundleCachePath instead of deprecated bundlePath

The worker.ts file was still using the old bundlePath property name in two places:
1. When destructuring config from getConfig()
2. When constructing the upload destination path

This was a critical runtime bug - when users only set serverBundleCachePath
(the new property name), the code would receive undefined for bundlePath,
breaking file upload functionality.

Changes:
- Line 121: Updated destructuring to use serverBundleCachePath
- Line 154: Updated path.join call to use serverBundleCachePath
