Refactors event handling and grid rendering

Improves calendar performance and data flow by streamlining event emissions and grid rendering logic.

- Replaces generic CONFIG_UPDATE events with REFRESH_REQUESTED
  for more specific refresh triggers.
- Removes redundant grid re-renders on DATE_CHANGED and
  WEEK_CHANGED events, delegating navigation to NavigationManager.
- Introduces VIEW_CHANGED and DATE_CHANGED events for calendar
  mode and date selection, respectively.
- NavigationManager now handles date validation.
- Moves rendering logic from NavigationManager to NavigationRenderer.
- Syncs scroll position based on PERIOD_CHANGED instead of
  NAVIGATION_ANIMATION_COMPLETE.

This change optimizes the calendar's responsiveness and reduces
unnecessary re-renders, leading to a smoother user experience.
