The split style's pull-to-expand fires the moment the drag clears its
threshold, and that turned out to be the better feel — so paging now does
the same everywhere: month, week and day.
Waiting for the lift meant the page sat still under a finger that had
already travelled far enough to ask for it, and the answer only arrived
once you let go, which reads as the view being slow rather than as a
deliberate commit. The trade is that a drag can no longer be taken back by
dragging the other way; once you have moved 24dp deliberately you meant it,
and the page you left is one swipe back.
The three views had three copies of the same detector, so this extracts one
rememberCalendarPageSwipe and the threshold constant beside it. It stays
horizontal-only on purpose: the week and day timelines scroll vertically
underneath, and a two-dimensional detector would claim those drags before
the inner scroll saw them. The month keeps its own axis-locking detector
because the split style needs the vertical axis, and now shares the
threshold.
