Implements edge scrolling functionality

Adds edge scrolling to automatically scroll the calendar
when dragging an event near the edges of the view.

This improves the drag-and-drop experience by allowing users
to move events beyond the visible area.

Removes auto-scroll logic from the event renderer, centralizing
the scrolling behavior within the new edge scroll manager.
