Backend Fix - Sync Model Changes

Problem

The backend was failing to start with a System.InvalidOperationException because the ZentralDbContext model had pending changes that were not captured in a migration.

Solution

1. Created a new migration SyncModelChanges to synchronize the database schema with the code.
   • Command: dotnet ef migrations add SyncModelChanges --project Zentral.Infrastructure --startup-project Zentral.API
2. Updated the database.
   • Command: dotnet ef database update --project Zentral.Infrastructure --startup-project Zentral.API

Status

• Create Migration
• Update Database
• Verify Backend Startup

The backend now starts correctly and listens on the configured port.
