Distinct from the existing "Année" filter (which restricts the view
to just that year): this re-centers the sliding window on 1 January
of the chosen year and scrolls there, while staying in the continuous
view -- scrolling still extends the window normally in both
directions, so overlaps between years stay visible, matching the
earlier stated preference for a continuous view over a filtered one.
Resets to the placeholder immediately after firing since it's a
one-shot action, not a sticky filter. Guards against racing the
"Année" watcher's own exitYearMode() when a year filter is already
active when the jump is triggered.
