fix: fetch instances

- Modified instanceInfo method to accept an optional array of instance names, improving flexibility in instance retrieval.
- Updated related controller and service methods to utilize the new instanceInfo signature, ensuring consistent handling of instance names.
- Enhanced error handling for non-existent instances when provided with specific names.
