Refactors calendar configuration and event handling

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.
