Add complete domain events dispatching infrastructure and critical event handlers for Identity module.
Changes:
- Added IMediator injection to IdentityDbContext
- Implemented SaveChangesAsync override to dispatch domain events before persisting
- Made DomainEvent base class implement INotification (added MediatR.Contracts dependency)
- Created 3 new domain events: UserRoleAssignedEvent, UserRemovedFromTenantEvent, UserLoggedInEvent
- Implemented 4 event handlers with structured logging:
- UserRoleAssignedEventHandler (audit log, cache invalidation placeholder)
- UserRemovedFromTenantEventHandler (notification placeholder)
- UserLoggedInEventHandler (login tracking placeholder)
- TenantCreatedEventHandler (welcome email placeholder)
- Updated unit tests to inject mock IMediator into IdentityDbContext
Technical Details:
- Domain events are now published via MediatR within the same transaction
- Events are dispatched BEFORE SaveChangesAsync to ensure atomicity
- Event handlers auto-registered by MediatR assembly scanning
- All handlers include structured logging for observability
Next Steps (Phase 3):
- Update command handlers to raise new events (UserLoggedInEvent, UserRoleAssignedEvent)
- Add event raising logic to User/Tenant aggregates
- Implement audit logging persistence (currently just logging)

Fixed 8 failing integration tests by addressing two root causes:
1. GlobalExceptionHandler returning incorrect HTTP status codes
- Added handling for UnauthorizedAccessException → 401
- Added handling for ArgumentException/InvalidOperationException → 400
- Added handling for DbUpdateException (duplicate key) → 409
- Now correctly maps exception types to HTTP status codes
2. Test isolation issue with shared HttpClient
- Modified DatabaseFixture to create new HttpClient for each test
- Prevents Authorization header pollution between tests
- Ensures clean test state for authentication tests
Test Results:
- Before: 23/31 passed (8 failed)
- After: 31/31 passed (0 failed)
Changes:
- Enhanced GlobalExceptionHandler with proper status code mapping
- Fixed DatabaseFixture.Client to create isolated instances
- All authentication and RBAC tests now pass

Implement environment-aware dependency injection to resolve EF Core provider conflict
in Integration Tests. The issue was caused by both PostgreSQL and InMemory providers
being registered in the same service provider.
Changes:
- Modified Identity Module DependencyInjection to skip PostgreSQL DbContext registration in Testing environment
- Modified ProjectManagement Module ModuleExtensions with same environment check
- Updated Program.cs to pass IHostEnvironment to both module registration methods
- Added Microsoft.Extensions.Hosting.Abstractions package to Identity.Infrastructure project
- Updated ColaFlowWebApplicationFactory to set Testing environment and register InMemory databases
- Simplified WebApplicationFactory by removing complex RemoveAll logic
Results:
- All 31 Integration Tests now run (previously only 1 ran)
- No EF Core provider conflict errors
- 23 tests pass, 8 tests fail (failures are business logic issues, not infrastructure)
- Production environment still uses PostgreSQL as expected
