NuGet package dependency

`Microsoft.IdentityModel.Abstractions` is a NuGet package dependency declared by the Pams.Business project. It supplies shared identity-model abstractions used by authentication and token-related components referenced during .NET build and restore operations.

## Usage

```ts
import { execFile } from "node:child_process";
import { promisify } from "node:util";

const execFileAsync = promisify(execFile);

async function buildPamsBusiness() {
  const projectPath = "Pams/Logic/Pams.Business/Pams.Business.csproj";

  const { stdout, stderr } = await execFileAsync("dotnet", [
    "build",
    projectPath,
  ]);

  console.log(stdout);

  if (stderr) {
    console.error(stderr);
  }
}

buildPamsBusiness().catch(console.error);
```

## AI Coding Instructions

- Keep `Microsoft.IdentityModel.Abstractions` as a NuGet package reference in `Pams.Business.csproj`; it is resolved by the .NET restore process.
- Do not import this package directly from TypeScript or JavaScript; consume it through .NET code that references the Pams.Business project.
- Run `dotnet restore` or `dotnet build` after changing package references so the dependency is resolved locally.
- Check compatibility with other `Microsoft.IdentityModel` packages before changing the package version or removing the reference.
