NuGet package dependency

`Microsoft.AspNetCore.SpaServices` is a NuGet package dependency in `Pams.Web.csproj` for ASP.NET Core single-page application support. It connects the ASP.NET Core host with SPA development and request handling behavior in the web project.

    participant Browser
    participant SpaApp as SPA client
    participant WebApp as Pams.Web
    participant SpaServices as Microsoft.AspNetCore.SpaServices

    Browser->>SpaApp: Load application
    SpaApp->>WebApp: Send API request
    WebApp->>SpaServices: Apply SPA service behavior
    WebApp-->>SpaApp: Return API response
    SpaApp-->>Browser: Render updated view
```

## Usage

```ts
async function loadPamsData() {
  const response = await fetch("/api/pams");

  if (!response.ok) {
    throw new Error("Unable to load Pams data.");
  }

  return response.json();
}

loadPamsData()
  .then((data) => {
    console.log(data);
  })
  .catch((error) => {
    console.error(error);
  });
```

## AI Coding Instructions

- Keep `Microsoft.AspNetCore.SpaServices` package configuration in `Pams.Web.csproj`.
- Route SPA API calls through ASP.NET Core endpoints rather than hard-coding external server addresses.
- Confirm SPA fallback behavior does not intercept API routes or static asset requests.
- Match client request paths, such as `/api/pams`, with routes registered by the ASP.NET Core application.
