ScrolledWindow handles PgUp/PgDown in bubble phase to trigger scrolling.
Which leads to inconsistent behaviour: scrolling when an event is focused,
and moving to the previous/next week when not. Explicitly handling the
shortcuts with a ShortcutController in capture phase makes it consistently
navigate to previous/next week.
Fixes#1409

Currently, at the top there is an always visible border
which, due to having the same colour as the drop shadow,
slightly interferes with how the drop shadow looks, while
more severely, the bottom bar's start is not easily
distinguishable from the week grid's end, as there is
no border at all.
Styling the scrolled content itself with a border
elegantly solves these two issues, because now a drop
shadow is drawn when scrolling in a direction is
possible, and a border is drawn otherwise.
