Introduced a many-to-many relationship between EventDefinition and Career entities, allowing for the association of multiple careers with an event. Updated the AppDbContext to include a DbSet for Careers and modified the EventDefinitionConfiguration to handle the new relationship. Enhanced the Create, Edit, and Details components to support input and display of related careers, including normalization and processing logic for career names. Updated the database schema to reflect these changes.
Created the EventOccurrence entity with properties for event details and added it to the AppDbContext. Updated the model snapshot to reflect the new entity and its relationships, ensuring proper database schema generation.
