[FEATURE] Enable health check for ASP.NET REST API

Add support for the ASP.NET health check feature to the REST API. This will provide an endpoint to monitor the API's health status and enable smoke testing after CI/CD runs.

#### Requirements
- Enable the ASP.NET Health Check feature.
- Expose a health check endpoint (e.g., `/health`).
- Ensure the health check includes basic verifications, such as API availability and necessary dependencies.
- The health check should be lightweight and suitable for automated smoke testing.

#### Example Implementation

Here is an example of how to enable a basic health check in an ASP.NET REST API:

```csharp
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Diagnostics.HealthChecks;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;

var builder = WebApplication.CreateBuilder(args);

// Add health checks to the service collection
builder.Services.AddHealthChecks();

var app = builder.Build();

// Map the health check endpoint
app.MapHealthChecks("/health");

app.Run();
```

In this example:
- A `/health` endpoint is exposed that checks the primary health status of the application.
- Additional health checks for dependencies (e.g., database, external services) can be added as needed.

#### Acceptance Criteria
- [ ] Health check endpoint is available and accessible.
- [ ] Basic API health status is reported.
- [ ] Health check can be used for automated smoke tests in CI/CD pipelines.
- [ ] Documentation is updated to specify the endpoint and its purpose.

#### Notes
- Consider future extensibility for adding checks for specific dependencies (e.g., database, external APIs).
- Ensure the health check endpoint does not expose sensitive information.
