[New Feature] Sync completed with errors. Check the log file.

Currently when a file upload fails, the below notification is shown in the GUI.

Failed items to upload to/from Microsoft OneDrive: 1
Failed to upload: ./Python/plotter/uploads/ScriptOutput/scriptoutput
Sync with Microsoft OneDrive has completed, however there are items that failed to sync.
To fix any upload failures you may need to perform a --resync to ensure this system is correctly synced with your Microsoft OneDrive Account

This could be improved by:

1. Showing the list of the files that failed the sync in the GUI
2. Displaying a button in the GUI to manually trigger a full re-sync.
