bug(ui): Back button on details page should be predictable with scroll restoration.

[elliotcourant]

Right now the back button is not actually a back button but is instead a link back to what it knows is the previous page. This way it works even if the URL loaded is direct to the detail and does not have any history.

Something should be added such that if the previous page does exist though and it is for that transactions path, then navigate(-1) should be used instead to perform proper scroll restoration.
