refactor(tui): trim the folder column change to what it needs

The path splitter is a one-line stdlib call with a single caller, so it
lives beside that caller as a private fn, without its own tests. The pane
tests assert the two columns in one screen fragment each, the end-offset
test keeps only the two cases the existing name tests do not cover, and
the key-handling test that repeated one of them goes. The website mock
splits on the backslash the same way its Info pane already does.
