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

Collapse triggers when progress > 0.25 (was 0.5). Expand triggers when
progress < 0.75 (1 - threshold), creating asymmetric thresholds that make
both fold and unfold easy to trigger with a short drag.

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.

Inject Clock into CalendarViewModel for testability, add kotlinx-coroutines-test dependency, replace placeholder test with real coverage for ISO week numbers, month day grids, page mapping, and utility functions.

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.

- Remove unused currentWeeksCount variable and onWeeksChanged callback
- Replace deprecated monthNumber with month.number (requires explicit import)
- Remove all @Suppress("DEPRECATION") annotations for monthNumber
- Convert double comparison to range check (today in weekMonday..weekSunday)

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.

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

- 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.
