Fixed #16000 - add S3 support for eula PDF downloads

[snipe]

This needs to be tested (and I'm having an issue on my local right now). This should fix #16000 though, enabled S3 downloads for EULA PDFs.

PR Summary

• Introduction of Conditional Check for S3 Private Filesystem
  A new condition has been added for the S3 Private Filesystem configuration intending to generate a temporary URL. This will be used for downloading the EULA (End User License Agreement) PDF which increases the access security level.

• Updating Method for S3 URL Redirection
  The method has been modified to redirect to the S3 URL if the filesystem is set to s3_private. This ensures efficient routing for data access and an enhanced user experience.

• Maintaining Download Response for Local Storage
  Download responses for files stored locally are being maintained amidst changes to the file path handling to sustain data consistency in local storage use cases. This means users can still access their files with improved precision even if saved locally.
