Update file transfer capabilities

[asamborski]

Summary

Removing SFTP and SCP limitations for short-lived SSH. Both are fully supported now 😊

Documentation checklist

• [Not yet, coming next!] Is there a changelog entry (guidelines)? If you don't add one for something awesome and new (however small) — how will our customers find out? Changelogs are automatically posted to RSS feeds, the Discord, and X.
• The documentation style guide has been adhered to.
