feat(views): optional jump-to-today button in the toolbar (#60)

Add a "Today button in toolbar" appearance toggle (default off). When on,
each calendar view (month/week/day/agenda) shows a persistent go-to-today
icon button in its top bar instead of the fade-in extended FAB, and the
FAB pill is suppressed. Same jump action, just always present.
