WPB-21660 [iOS] Implement versioning

Issue

This PR introduces File versioning, specifically the ability for a user to :

• see all versions for a file
• restore a previous version

note: video taken before merging latest changes from develop also opening and viewing a version has been recently removed from the implementation
https://github.com/user-attachments/assets/6c2defce-cb7b-414b-94b8-00c069cd2d1a

Testing

• select version history on the files list (item ellipsis)
• see all versions from that file
• restore the version it should show up as the most recent version
• edit and save a file on the Web, it should show up on the list (polling mechanism) as the current version
• going back to the Files list, when previewing the file, the latest file should show up correctly
• if on the Files list, and the document is edited on Web, we need to pull to refresh to see the correct file (no polling).
