feat: add restore file from files_tab

[Edgpaez]

First of all, thank you for the time and effort you've put into lazyjj !

This implements the equivalent to jj restore file.
I tried to follow #146.
I have been using daily a fork with this commit for over a week and found no problems with it

This includes the change from #183 to send the path with path: so errors don't occur for paths with :

Happy to change based on feedback :)

I also changed this so files with double quotes can be restored.

Nice, but When showing files from a different rev than @, this should either pass in that revision using the --changes-in option, or there should be a safe guard against running it on revisions other than @.

thanks again for reviewing @dotdash.
as far as I can see, the files tab always shows the changes from @: https://github.com/Cretezy/lazyjj/blob/main/src/app.rs#L109-L113

It seems like this was not always the case... and I can see the value in showing it for the selected rev. Maybe we can address that in another PR? we would also need to safe guard untrack and any other commands we want to run on a file.
