Extend FileExplorer to Browse S3 and ADLS Paths

[Edwardvaneechoud]

Allow users to visually browse their cloud storage just like a local filesystem.

• Path Detection: Modify the existing FileExplorer service to recognize cloud URI schemes (e.g., s3://, abfs://).

• Cloud Browsing Logic: When a cloud path is detected, the service should use the appropriate library (s3fs or adlfs) to list the contents of the bucket or container.

• Consistent UI: The results from browsing cloud storage must be returned in the same FileInfo format as local files to ensure they are displayed correctly in the UI.
