Apply consistent formatting: import ordering, line wrapping,
indentation, and XML normalization. No functional changes.

Quick swipe now snaps to the target state regardless of progress position,
matching the behavior of HorizontalPager's fling logic. Uses VelocityTracker
to measure release velocity and a 800 dp/s threshold (FLING_VELOCITY_THRESHOLD_DP).
Slow drags still use the positional COLLAPSE_THRESHOLD (50%) as before.

The fixed DRAG_RANGE_DP=200dp caused the collapse progress to advance faster
than the visual height change, making the calendar feel like it "outruns" the
finger. Now dragRangePx is computed as (weeks-1)×rowHeight, matching the
actual visual height delta during collapse so finger movement maps 1:1 to
visual change.

gridHeightPx changed from derivedStateOf to direct computation because
derivedStateOf cannot track non-State local variable changes, causing
gridHeightPx to not update when rowHeightPx transitions from 0 to measured value.

Move shared constants and helper functions into CalendarUtils.kt,
replace manual state synchronization with derivedStateOf in
CalendarViewModel and UI composables.

Use currentPage instead of settledPage for interpolatedWeeks calculation
to prevent gridH jumps during month transitions. When offsetFraction is
near zero, compute weeks from currentPage rather than stale callback
state. Remove all debug println statements and TAG constants.

- 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()

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.
