fix(calendar): the docked pane's date fits beside its buttons

In the pane's agenda and day views the title had about seventy pixels
and read "Sep 24, 20…", now on the surface every desktop opens on. The
pane drops the year while it is this one and keeps it for any other.
Week and month widen the pane to fit them, and the full page has room.
