test(document): rewrite FileSwitcherStrip test with behavioral assertions

Replaces 3 setTimeout sleeps with vi.waitFor on document.activeElement
during keyboard nav, and converts 2 .not.toThrow smoke tests on the
prev/next buttons into no-op assertions: with a single file in the
strip the active chip stays selected and onSelect is not invoked.
