While reviewing #4208, I had a bit of a headache figuring out the
sliceMultiDaylogic. I cleaned that part up to make it easier to follow and structurally clearer. In doing so, I noticed the previous calculation was wrong in two edge cases:These cases are easy to miss because they are rare and only show up in specific time windows or timezone transitions.
The logic now splits multi-day events by the calendar days they actually cover and handles the boundary cases correctly.
