The slide-out panel gains a "View" section mirroring the top-bar switcher
pill: three NavigationDrawerItems (Month/Week/Day) with the current view
highlighted; tapping one selects that view and closes the drawer. The pill
stays as-is for quick cycling.
Centralise each view's label + icon as labelRes/icon extensions on
CalendarView so the pill and the drawer share one mapping. The drawer's
"Today" jump is dropped — the top-bar Today action and error-state retry
still cover it.
