Refactors calendar initialization with factory

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.

+## Aktuel Arkitektur Status
+
+### Factory Pattern
+- ManagerFactory håndterer manager instantiering
+- Proper dependency injection via constructor
+
+### Event-Driven Communication
+- EventBus koordinerer kommunikation mellem managers
+- NavigationRenderer lytter til WEEK_INFO_UPDATED events
+- EventRenderingService reagerer på GRID_RENDERED events
+
+### Separation of Concerns
+- Managers håndterer business logic
+- Renderers håndterer DOM manipulation
+- EventBus håndterer kommunikation
