tui: skip path-quoting tests on windows

normalisePathToken's heuristic only fires for unix-shaped paths
(leading /, ~, or file:// with a / path). On Windows, t.TempDir()
returns paths like C:\Users\RUNNER~1\AppData\Local\Temp\...
which never match those prefixes, so the test inputs never get
quoted and every assertion fails. The function is unix-only by
design (drag-and-drop on macOS/Linux); skip the test on Windows
rather than carry a parallel Windows test that would just
duplicate platform-specific quoting logic.
