Refactors calendar type to calendar mode

Updates the codebase to utilize `CalendarMode` instead of the deprecated `CalendarType`.

Simplifies `CalendarConfig` by removing legacy methods and related type aliases, enhancing code maintainability and clarity.

Improves event rendering by ensuring `GRID_RENDERED` events include explicit start and end dates, preventing errors and ensuring correct data filtering.
