The scrolling styles navigate by scroll position and never set the paged
month, so it sat wherever paged navigation last left it — today's month
on a fresh open. Switching to a paged style, or reseeding the other
scrolling style's list state (both read off it), snapped back there
instead of holding the month on screen.
Track the paged month to the visible month while a scrolling style is
up, realigning the split selection alongside it so landing on Split
shows a live day in the month you were viewing rather than a stale,
off-month one.
