Add S3 Configuration and Connection Status to Virtual Group Web Page

[kruall]

Currently, the configuration and status of the S3 connection are not visible on the virtual group web page.
We should add this information to improve transparency and allow users to monitor the S3 setup (e.g., connection health, bucket details) directly from the UI. A dedicated section for S3 configuration would help users troubleshoot and verify settings without needing to rely on external tools or logs.
