Update cpptango/TangoTest for class_factory removal
This version includes the removal of class_factory code from cpptango. And uses TangoTest 3.13 which supports that as well.
All dependencies in pixi.lock were updated as well.
pytest 9.0 added a terminal progress indicator, but this doesn't work nicely (at least on iTerm2), so we add an option to disable it.
(We still need !946 (merged) for CI to pass)
