Update server bundle path resolution to utilize public output path

- Modified the candidate paths logic to include the public output path from PackerUtils when `enforce_private_server_bundles` is not active.
- This change enhances the flexibility of server bundle path resolution, ensuring that the system can effectively locate bundles in the public directory when appropriate.

This update builds on previous enhancements to improve asset management and aligns with the ongoing refactoring efforts in the project.
