feat(calendar): replace CSS-transform zoom with GSAP flying-rect animation and scope data to year

- Add CalendarDateRange input to GraphQL schema; server resolver now accepts from/to params
- Frontend query sends year-scoped date range variables reactively
- Rewrite zoom-in/zoom-out animations using GSAP flying-rect overlay (650ms vs 2400ms)
- Add flying-rect element to CrmCalendarPanel with proper CSS
- Remove old calendarSceneTransformStyle CSS-transition approach
- Add calendarKillTweens cleanup in onBeforeUnmount
