This commit updates the EventOccurrenceService to replace mock data with a database-backed implementation for retrieving event occurrences. The GetEventOccurrencesAsync and GetEventOccurrencesForDateRangeAsync methods now utilize Entity Framework to fetch data from the AppDbContext, enhancing the service's functionality and ensuring accurate event management.
Enhanced the application's service layer by adding FormValidationService and EventDefinitionService to the dependency injection container in Program.cs. Updated Create, Edit, and other relevant components to utilize these services for improved form validation and event processing functionality.
Introduced a new Event Calendar component that displays scheduled events using the Heron.MudCalendar. Implemented IEventOccurrenceService to fetch event occurrences, and added mock data for initial testing. Updated navigation menu to include a link to the Event Calendar.
