fix: return original error in PathOrCidPath fallback (#11059)

PathOrCidPath was returning the error from the second path.NewPath call
instead of the original error when both attempts failed. This fix preserves
the first error before attempting the fallback, ensuring users get the
most relevant error message about their input.
