Autosave: improve the notice when the sessionStorage autosave is different than the content.

Browse Source 
- Make it higher priority than the server autosave.
- Change it so the editors undo and redo can be used.
- Replace the restore link with a button.
- Add better explanation/help.

See #37025.
