feat(calendar): seamless zoom animation with clone-and-swap + full-area coverage

Zoom-in: fade siblings → fade source content → clone source style to fly-rect →
hide source → animate fly-rect to viewport → switch view → fade in new content.

Zoom-out: fade scene → show fly-rect at viewport → switch view → clone target
style → animate fly-rect to target → fade in scene.

Full-area: all views (month/week/day) now fill 100% of container height.
Month grid rows stretch equally, day cells fill row height, depth layers flex.
