Thanks for doing the testing. You are probably right that normal distribution is not an appropriate assumption.

Your suggested tweaks to the confidence interval ranges would help the confidence intervals themselves, but I'm not sure what to do as a test of whether the difference is significant. Just having two confidence intervals is not necessarily sufficient for that, or at least, the t-test itself doesn't work that way.
