Add unit tests for KubernetesCluster, Tenant, ServiceInstance, and RegisterClusterHandler

- Implement tests for KubernetesCluster including registration, connectivity status, and error handling.
- Create tests for Tenant creation, member management, and status changes.
- Add tests for ServiceInstance provisioning and state management.
- Introduce RegisterClusterHandler tests to validate registration requests and error scenarios.
- Set up project files for new test projects with necessary dependencies.

 ## Architecture
 
-### Modular Monolith with Blazor
+### Microservices with Blazor BFF
 
-EntKube is a **modular monolith** — a single deployable Blazor application with clearly separated domain modules internally. This keeps deployment simple while maintaining clean boundaries between concerns.
+EntKube follows a **microservices architecture** with a Blazor BFF (Backend-for-Frontend) as the user-facing entry point. Each service owns its bounded context, has its own data store, and can be deployed and scaled independently. This is NOT a nano-services architecture — we split by meaningful business boundaries, not by technical layers.
 
 #### Core Principles
-- **Domain modules within one application**: Each business capability (cluster management, service provisioning, tenant management, etc.) lives in its own namespace/folder but deploys as part of the single application
+- **4 services, each with a clear responsibility**: Web (BFF), Clusters, Provisioning, Identity
-- **Clear module boundaries**: Modules communicate through well-defined interfaces — never reach directly into another module's internals
+- **Each service owns its data**: No shared databases between services
-- **Shared database with schema separation**: The single application owns its database, but each module owns its tables/schema area
+- **Services communicate via HTTP APIs**: Simple REST calls between services, with resilient retry policies
-- **Extract to a service only when necessary**: If a module genuinely needs independent scaling or a separate lifecycle, extract it then — not before
+- **SharedKernel for contracts only**: Shared types (Result, ApiResponse, base Entity) live in a shared library — but no shared business logic
+- **Feature folders over layer folders**: Each feature is a vertical slice (handler + endpoint + related types in one folder)
 
-#### When to Extract a Module to a Separate Service
+#### Service Boundaries
-- The module has drastically different scaling requirements
+
-- The module needs to be deployed on a different cadence
+| Service | Responsibility | Port (dev) |
-- The module introduces an external integration that benefits from fault isolation
+|---------|---------------|-------------|
+| **EntKube.Web** | Blazor BFF — serves UI, proxies API calls to backend services, owns user auth session | 5000 |
+| **EntKube.Clusters** | Kubernetes cluster registration, health monitoring, API connectivity | 5010 |
+| **EntKube.Provisioning** | Shared service lifecycle (MinIO, CNPG, Keycloak) — provisioning, reconciliation, teardown | 5020 |
+| **EntKube.Identity** | Tenant management, user membership, roles, Keycloak integration | 5030 |

 ### Communication Patterns
-- Internal module communication via dependency injection and in-process calls
+- **Service-to-service**: HTTP REST via typed HttpClient with Polly retry policies
-- Kubernetes API communication for cluster management operations
+- **BFF-to-service**: The Web BFF proxies user requests to the appropriate backend service
-- HTTP APIs exposed for external integrations
+- **Kubernetes API**: The Clusters service communicates with k8s API servers using the official .NET client
-- Use resilient connections with retry policies (Polly) for external calls
+- **Async workflows**: Background services within each microservice handle reconciliation loops (e.g., provisioning, health checks)
+- **No message bus yet**: Start with synchronous HTTP; extract to async messaging (NATS, RabbitMQ) only when proven necessary
