Streamlines calendar configuration by adopting a singleton pattern for consistent access and simplifies event handling.
- Removes direct `CalendarConfig` dependency injection in favor of the `calendarConfig` singleton, reducing code complexity.
- Replaces specific event emissions for grid, date, and resource settings updates with a general `REFRESH_REQUESTED` event.
- Updates event names to be more descriptive and consistent ("NAVIGATION_COMPLETED", "PERIOD_INFO_UPDATE").
- Removes the need to pass the calendar config to renderers since it is now a singleton.
This improves code maintainability and simplifies the event emission process.
Improves drag and drop performance by caching DOM elements and consolidating position calculations.
This reduces redundant DOM queries and optimizes event handling for smoother user interaction.
Also leverages `DateCalculator` for date/time conversions.
Cleans up the codebase by removing unnecessary console log statements.
These logs were primarily used for debugging and are no longer needed in the production code.
This reduces noise in the console and improves overall performance.
Introduces a DragDropManager to handle event dragging and dropping, replacing the ColumnDetector.
This change centralizes drag and drop logic, improving code organization and maintainability.
The EventRenderer now uses the DragDropManager's events to visually update the calendar during drag operations.
Removes ColumnDetector which is now replaced by the drag and drop manager.
