feat(ui): shadcn range-calendar primitive over reka-ui RangeCalendarRoot

Port of ui/calendar onto reka-ui's RangeCalendar* parts, same slot shape.
The cell trigger gains range states — accent tint for the nights inside
the range, primary pills on the two ends — and a real unavailable look
(struck through, muted, not a pointer target).
