Links of files from FileSideBar remains unchanged after changing the Site URL

Description:

I changed the reverse proxy url of rocket, say from chat.***.com to chat.***.dev，and changed the Site URL from the rocket's administration-General-SiteUrl settings accordingly. Everything works fine but the FileSideBar, which still points files to the old url.

The file in the message side is correctly changed to
https://chat.***.dev/file-upload/[fileID]/[filename]?download

but the file in the FileSideBar remains
https://chat.***.com/ufs/FileSystem:Uploads/[fileID]/[filename]
If change the link manualy in the browser, I can download it.

Client Setup Information

• Desktop App or Browser Version: Both

Start by tracing the FileSideBar entry point that builds file links, then compare its URL construction with the message-side file-upload link described in the issue. Done means FileSideBar links use the current Site URL after it changes, while preserving the existing file identifier and filename behavior.
