Replace internal rowHeightPx measurement with external rowHeightPx
parameter passed from CalendarMonthView. This eliminates the mismatch
between outer gridHeightPx (based on shrinking container) and inner
totalHeightDp (based on independently measured row height), which was
causing visual jitter during collapse animation.
Remove onRowHeightMeasured callback, TAG constant, and debug printlns
from CalendarMonthPage as part of this refactor.

Calculate actual weeks needed per month and interpolate row count during
page swipe so BottomCard follows the grid height smoothly. Remove debug
println statements.

Select the Monday of the week when WeekPager changes, and the 1st of
the month when CalendarPager changes, so the selected date always
matches the visible page.

Switch CalendarMonthPage from Column to Box with calculated y positions per row,
enabling precise height computation that aligns with CalendarMonthView's
BottomCard positioning. Simplify cardTopPx calculation by deriving grid height
from the same formula instead of tracking expandedCalendarHeightPx separately.

Non-selected rows now compress their height proportionally with
collapse progress, replacing the previous overlay-based approach.
Remove KDoc that described the old overlay behavior.

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.

- Add KDoc to all public Composable functions with parameter descriptions
- Add inline comments for non-obvious algorithms (42-cell grid, pager mapping)
- Add @Suppress reason comments for monthNumber deprecation
- Document collapseProgress range and physical meaning
- Add named constant comments for START_PAGE
- Add Preview name to App()

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.
