Introduces a new manager responsible for detecting the column the mouse is currently over.
This enables event cloning and repositioning within the calendar columns during drag operations, enhancing the user experience.
Centralizes all date calculations into a new `DateCalculator` class for better maintainability and consistency.
Ensures correct ISO week handling (Monday as the first day) throughout the calendar.
Updates `CalendarConfig` to use ISO day numbering (1-7 for Mon-Sun) for work week definitions.
Fixes issue where date calculations were inconsistent.
Enhances event rendering and navigation.
Updates navigation logic to use pre-rendered events.
Removes the need for `CONTAINER_READY_FOR_EVENTS` event.
Implements a factory pattern for manager creation and
initialization, improving dependency management and
extensibility.
This change replaces direct manager instantiation with a
`ManagerFactory` that handles dependency injection. This
enhances code organization and testability. It also includes
an initialization sequence diagram for better understanding
of the calendar's architecture and data flow.
