ci: raise e2e-ios job timeout to 50min for detox retries

With --retries 2 a single failing attempt pushes total wall time past
the 30min job timeout, which cancels the run mid-retry (run 28921995046
died at 32min in the Detox step). Also upload artifacts on cancelled()
so timeout kills still leave diagnostics.
