Selected row now moves up via offset + zIndex to cover other rows, which
stay in place. Collapse offset calculation excludes MonthHeader and
WeekdayHeader heights so only the grid portion is collapsed.

When rowHeightPx is 0 (first frame), use aspectRatio-based natural
height instead of collapsing to 0.dp, preventing a visible flash.

Use expandedCalendarHeightPx to preserve full height during collapse animation,
and compute cardTopPx based on collapse state instead of offset arithmetic.

ViewModel now exposes onDrag/onDragEnd so BottomCard drives the
collapse animation via detectVerticalDragGestures instead of a
discrete collapse() call. Drag maps to 0–1 progress over 200dp;
on release the animatable snaps to the nearest end with spring.

Add isCollapsed/collapseProgress state to CalendarViewModel for toggling
between month and week views. CalendarMonthPage animates non-selected
weeks out with offset and alpha. Introduce WeekPager for single-week
HorizontalPager and BottomCard with drag-to-collapse gesture.

Remove foojay-resolver-convention plugin to avoid downloading JDK from
foojay.io. Simplify gradle-daemon-jvm.properties to only specify
toolchainVersion=21. Upgrade JVM target from 11 to 17 in composeApp.
